	tabs as indentation. Paragraphs are generated by "\n\n\n\n".

	* src/bin/geomview/common/pickfunc.h:
	Execute 3d picking code if pn <= 4 (i.e. the 3d block is also
	responsible for void pick events).

	* src/bin/nose/nose.c: Add myself to the copyright notice.

	* src/lib/gprim/geom/Makefile.am: Add nodedata.h to library sources.

	* src/lib/mg/x11/mgx11windows.c:

	Pick events now use the new LVARARRAY stuff; this also means that
	picking of ND-objects is now fully (mmh, really?) supported. At least
	Nose seems to do the right things ...

	* src/bin/crayola/Makefile.am:
	First link with libgeomview, then with Tcl/Tk.

	* src/bin/geomview/common/drawer.c:
	drawer_dgeom(): Use NULL arg to GeomBSPTree(..., BSPTREE_CREATE) to
	trigger recreation.

	* src/bin/geomview/common/drawer.h, src/bin/geomview/common/ndshade.c:
	Comment out the last relicts of the most recent optimization attempts.

	Implement new LVARARRAY lisp object: variable sized arrays, the
	argument parsing code just allocats as much space as needed. This
	comes in very handy -- e.g. -- for interest in pick objects.

	* src/lib/oogl/lisp/Makefile.am: Let clisp.c depend on lisp.h.

	* src/lib/oogl/lisp/Headers: lisp2.h was a duplicate, remove it.

	Fix BSP-tree invalidation.

	* src/lib/gprim/npolylist/nplcreate.c:

	* src/lib/geomutil/crayplutil/Makefile.am, src/lib/geomutil/crayplutil/crayNPolylist.c, src/lib/geomutil/crayplutil/crayola.c, src/lib/geomutil/crayplutil/crayolaP.h:
	Add colouring support for NPolyList objects. Only NDMeshes are still
	missing. But the ND-Mesh concept is broken anyway.

	* src/lib/geomutil/crayplutil/crayVect.c:
	Get rid of a compiler warning.

	* src/lib/geometry/hpointn/hpointn.h:
	HPt3NTransform(): used wrong permutation (inverted).

	* src/lib/geometry/transform3/tm3print.c:
	Geeh, this stuff still used printf instead of fprintf.

	* src/lib/geometry/transformn/transformn.h: Formatting of comments.

	* m4/geomview.m4: Check for Geomview in bindir first.

	Issue an error if non-blocking IO flags are not defined.

	* src/bin/geomview/common/comm.c:
	emodule_run() tiny fixes, shouldn't change anything.

	* data/Makefile.am: Distribute some more texture images.

	* src/lib/geometry/hpoint3/hpoint3.h:
	Hpt3MinMax(): catch the w == 0 case.

	* data/geom/textured/themi.bez: Use texturing.

	* data/geom/textured/Antenna.geom, data/geom/textured/GCGball, data/geom/textured/NASA.pgm.gz, data/geom/textured/dodec.off, data/geom/textured/geologo.pgm.gz, data/geom/textured/grid.pgm.gz, data/geom/textured/lunar-t.oogl, data/geom/textured/square.off, data/geom/textured/themi.bez, data/geom/textured/white.pgm.gz:

	attempt to make the stuff 64-bit clean (actually: to make it
	independent from sizeof(void *)).

	* src/lib/oogl/refcomm/reference.c: No longer needed (inlined).

	* src/bin/geomutil/bdy/Makefile.am, src/bin/geomutil/bdy/drawbdy.sh:

2007-05-15  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/bin/geomutil/vrml2oogl/lib/QvPList.c++: Another AIX fix.

	* src/lib/mg/opengl/mgopengldraw.c:
	Never release stuff without testing ...

	* data/Makefile.am, data/shaders/Makefile.am:
	Use "dist_" prefix instead of EXTRA_DIST for .._DATA stuff, distribute
	the compiled shader source.

	* src/lib/geometry/cmodel/cmodel.c:
	Do not use alloc for large arrays. Don't.

	* src/lib/gprim/geom/bsptree.c, src/lib/mg/opengl/mgopengldraw.c:
	Although otherwise documented the "vertex_data" argument to the GLU
	tesselator combine-callbine does _NOT_ always contain valid
	pointers. Also make sure that a zero homogeneous component does not
	produce NaNs; this leads to memory corruption or infinite loops in the
	tesselator.

	* src/lib/gprim/mesh/meshdraw.c:
	cm_mesh_draw() needs the per-point normals.

	* configure.ac, doc/Makefile.am, src/bin/geomutil/oogl2rib/oogl2rib.c, src/bin/geomutil/plutil/polymerge.c, src/lib/oogl/util/porting.h:

	context has gone.

2007-04-16  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	Need to use LDFLAGS; the library path passed to AC_CHECK_LIB() in the

	linker paths are position sensitive.

2007-04-15  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/oogl/util/iobuffer.c:

	Support 3d-snapshots for Insts (colored or not).

	* src/lib/gprim/npolylist/nplcreate.c:
	CR_POINT: homogeneous component is now at index 0 for ND stuff.

	* src/lib/gprim/npolylist/nplcopy.c:
	Only copy per-vertex colour if they are present.

	* src/lib/gprim/geom/geomstream.c:
	GeomStreamOut(): _always_ surround geometries by braces, some
	geometries (INSTs) have a variable number of "sections" which may be
	there or not.

	* src/bin/geomview/common/worldio.c:
	save_dgeom_geom(): only decrease the pool-level is wrap == true.

	* src/bin/example/Makefile.am:

	FreeBSD seems to work now (with this emodule)

	* m4/check-package.m4: Cosmetics.

	* m4/check-package.m4, src/bin/example/Makefile.am:
	We need to be a little bit more careful when checking for packages;

	HandleReferringTo(): ref-count cleanups introduced some bugs which
	made it impossible to read from a named pipe, fix that (always return
	with a handle if the file could be opened, even when it does not have
	(yet) data available).

	* data/Makefile.am: dodec.vec belongs to cplxview.

	* src/bin/nose/nose.c: Fix some compiler warnings.

2007-04-03  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/bin/geomview/x11/Makefile.am, src/bin/labeler/Makefile.am, src/lib/mg/x11/Makefile.am:
	Use X_CFLAGS; on older systems the X11 headers are still below X11R6/include/

	* configure.ac:
	Do not try to generate empty archives, this is not supported on all
	platforms. Check for compressBound() if zlib is found (then it is
	pre-1.2.x). Check for malloc.h and mallinfo() (debugging only).

	* data/shaders/Makefile.am: Forgot to add .sdl files to clean-local:

	* configure.ac:
	AC_CHECK_TYPES takes a comma separated list. Gnah. Autoconf is really
	inconsistent.

2007-04-02  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/bin/crayola/.cvsignore: Ignore .geomview.

	* m4/geomview.m4: Fix help text (kill reference to "example" emodule).

	* src/lib/gprim/geom/Makefile.am:
	bsptree.c needs the correct path to the glu.h header file 'cause it is
	using the GLU tesselator for complicated polygons.

2007-03-24  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* NEWS, doc/geomview.texi:
	Docment most recent translucency progress (by means of the GLU tesselator).

	* src/lib/gprim/geom/bsptree.c:
	Use a very large floating point tolerance (1e-3). This still seems to
	give good results in most cases, and prevents consumption of
	tremendous amounts of memory for translucent ND-objects and for
	Adrian's fancy self-intersecting polygons.

	* src/lib/gprim/geom/bsptreeP.h, src/lib/gprim/geom/draw.c, src/lib/gprim/geom/geomclass.h, src/lib/gprim/mesh/meshdraw.c, src/lib/gprim/ndmesh/ndmeshdraw.c, src/lib/gprim/npolylist/npldraw.c, src/lib/gprim/polylist/pldraw.c, src/lib/gprim/quad/quaddraw.c:
	Various ND-viewing translucency fixes; the stuff was broken again. Gnah.

	* src/lib/oogl/util/dbllist.h:
	New function DblListMove(): move the entire list from one head to
	another (this implies adjusting the back pointers to the list head as
	well 'cause it is a doubly linked list).

	* src/lib/mg/common/mg.c:
	Fix of a very silly beginners bug. What a shame.

2007-03-23  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/mg/opengl/mgopengldraw.c:
	Clean up of the "tricky" polygon code.

	* src/lib/gprim/geom/bsptree.c:
	Give the GLU tesselator the (already computed) normal.

	* src/lib/gprim/geom/bsptree.c:
	Use the GLU tesselator for non-convex quadrilaterals and for all
	polygons with more than 4 vertices. Should still need some performance
	tuning (e.g. we should pass the polygon normal to the tesselator etc.)

	* src/lib/gprim/geom/bsptree.c:
	Untested "#if 0"ed GLU tesselation for non-convex or non-flat polygons.

	* configure.ac, src/lib/gprim/geom/bsptree.c, src/lib/mg/opengl/mgopengldraw.c:
	Define HAVE_LIBGLU is that library is actually there, only compile
	trickypolygon() if GLU is found.

	The stuff still needs cleanup. The first attempt at the combine
	callback was really incomplete (textures, colors etc); and it could
	probably be sped up a little bit.

	First attempts to use the GLU tesselator for the BSP-tree stuff.

	* src/lib/gprim/discgrp/Makefile.am, src/lib/gprim/discgrp/discgrp.5gv:

	* src/bin/nose/Makefile.am: Typos.

	* data/Makefile.am:
	Move NDview data to NDview module where it belongs to.

	* configure.ac: Get rid of "foreign" automake flag.

	* README, configure.ac, src/bin/Makefile.am: Add nose emodule.

	* src/bin/geomutil/math2oogl/Makefile.am: Add man-page to EXTRA_DIST.

	* src/bin/nose/.cvsignore, src/bin/nose/Makefile.am, src/bin/nose/nose.1gv, src/bin/nose/nose.c:
	Nose module / example, debugging for picking.

	* m4/check-package.m4, m4/geomview.m4:
	Writing autoconf test is really a little bit complicated ...

	* m4/geomview.m4:
	Check also in standard places for geomview include files.

	Give all manual pages a gv suffix, some of the names are just too short.

	* doc/README.gvplot: Initial revision.

	* .cvsignore: Blah.

	* src/lib/Makefile.am: Versioning.

	* doc/version.texi: Update.

	* doc/Makefile.am: Use globally defined docdir.

	* README: Update.

	* configure.ac: No longer use  /usr/local/Geomview/ as default prefix.

	the GV_INIT_GEOMVIEW() macro.

	* NEWS, configure.ac: Call the beast 1.9.0

	* m4/geomview.m4:
	Small fixes (check for -lm, math.h, other minor stuff).

	* m4/geomview.m4, m4/set-prefix.m4: Some fine-tuning

	* src/bin/example/Makefile.am: Emodule definition stuff.

	* README: Cosmetics.

	* data/shaders/Makefile.am:
	Add blue-moon compiled shaders to EXTRA_DIST.

	* src/lib/oogl/util/Makefile.am: Add freelist.h to sources.

	* m4/geomview.m4: Feature local installation.

	* m4/check-package.m4, m4/geomview.m4, src/bin/example/Makefile.am:
	Autoconf madness.

	* src/bin/cplxview/Makefile.am, src/bin/example/Makefile.am, src/bin/flythrough/Makefile.am, src/bin/ginsu/Makefile.am, src/bin/graffiti/Makefile.am, src/bin/hinge/Makefile.am, src/bin/stereo/Makefile.am, src/bin/sweep/Makefile.am, src/bin/tackdown/Makefile.am, src/bin/transformer/Makefile.am:

	External gvemodules-xforms and gvemodules-tcltk packages.

2007-03-21  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/bin/NDview/Makefile.am, src/bin/ndutils/Makefile.am:
	Emodule strip-off should be finished now.

	* src/bin/ndutils/GeomExtentDirection.c: Cosmetics.

	* Makefile.am:
	Also install the private header files to enable stripping off emodules
	into separate package; private header files go to PKGINCLUDEDIR/private/

	* src/bin/Makefile.am:
	Remove NDview and ndutils, moved to a separate package.

	* doc/geomview.texi: Add some more cross-references for GCL commands.

	* doc/geomview.texi:
	Convert the GCL reference into subsections; the stuff can now be
	referenced and there is a menu node for each command.

	* doc/geomview.texi: Cosmetics

	* doc/geomview.texi: Forgot a closing bracket.

	* doc/geomview.texi, doc/version.texi, src/bin/geomview/common/comm.c:
	New command (hdelete [type] name) which can be used to actually delete
	a named global handle.

	* src/lib/gprim/geom/delete.c, src/lib/oogl/refcomm/handle.c:
	HandleRefIterate(), HandlePoolIterate() were not safe w.r.t. to the
	deletion of handles. Fix that.

	* src/bin/geomview/common/comm.c:
	commandclose(): should we really keep Pools with command-language? ATM
	I'm calling PoolDelete(). Mmmh.

	* src/bin/geomview/common/worldio.c:
	Lwrite(): also delete the tempoaray pool.

	* src/bin/geomview/common/lang.c:
	Lwrite_handle(): don't forget to delete the temporary pool.

	* src/bin/geomview/common/drawer.c:
	Lwrite_comments(): also delete the temporary pool. What else.

	* src/bin/geomview/common/comm.c:
	Slight changes for reading from command strings.

	* src/lib/oogl/refcomm/streampool.c:
	HandleReferringTo(): accessing a handle via ": blahhandle"
	automatically converts "blahhandle" into a global one.

	PoolClose(): revert back to not deleting the closed Pool. But maybe we
	should get rid of all the opened emodule pools nevertheless ...

	* src/lib/oogl/refcomm/handleP.h:
	Move the list-node to the top of the structure; this way (hack!) we
	can use the double-list node for the free-list without overwriting the
	"deleted" tag.

	* src/lib/oogl/refcomm/handle.c:
	HandleCreateGlobal(): do not reset the attached object when converting
	a temporary handle to a permanent one.

	* src/lib/gprim/geom/geomstream.c:
	GeomInvokeTranslator(): do not forget to really delete the temporary pool.

	* src/bin/geomview/x11/gvsave.c:
	PoolClose() takes care of stdout/stdin for itself.

	* src/lib/gprim/discgrp/dgclass.c, src/lib/gprim/discgrp/dgcreate.c, src/lib/gprim/discgrp/dgstream.c, src/lib/gprim/discgrp/discgrp.h, src/lib/gprim/discgrp/discgrpP.h:
	Sanitize the handling of geom, camgeom, ddgeom and their associated
	handles. Define a Get() method, so maniview no longer needs to access
	private data-structures.

	* configure.ac, src/lib/oogl/util/porting.h:
	Should use AC_CHECK_DECLS() before defining proto-types. The mere fact
	the function does not exist as a symbol does not mean that it is not declared.

	* m4/geomview.m4: Use GeomGet()/GeomSet() instead of accessing private
	data-structures. Make sure the damn stuff compiles as external module,
	outside the Geomview source-tree.

	* m4/geomview.m4: Fix unbalanced if-fi

	* Makefile.am, configure.ac, data/shaders/Makefile.am, geomview.sh, m4/geomview.m4, src/Makefile.am:
	Build system fixes.

	* m4/geomview.m4: Optionally check for the version of Geomview.

	* src/bin/NDview/Makefile.am: Cosmetics.

	* m4/withtool.m4: CHECK_PROG/PATH_PROG duality.

	* m4/withtool.m4: Absolute/relative path-name support.

2007-03-20  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* m4/withtool.m4, m4/geomview.m4: Initial revision.

	* src/lib/mg/opengl/mgopengldraw.c:
	Back-face culling cannot work with transparency, so disable it while
	drawing translucent facets.

	* src/lib/gprim/geom/geomclass.h, src/lib/gprim/inst/instcreate.c, src/lib/oogl/lisp/Makefile.am, src/lib/oogl/lisp/lisp.c, src/lib/oogl/refcomm/handle.c, src/lib/oogl/refcomm/streampool.c, src/lib/oogl/util/Headers, src/lib/oogl/util/freelist.h, src/bin/geomview/common/lispext.c, src/bin/geomview/common/lispext.h, src/lib/geometry/hpointn/hpointn.h, src/lib/geometry/ntransobj/ntransobj.c, src/lib/geometry/transformn/transformn.h, src/lib/geometry/transobj/transobj.c, src/lib/gprim/geom/delete.c:
	Implement a simplistic free-list approach for small objects which are
	allocated/deallocated very often.

	* src/lib/gprim/geom/bsptreeP.h, src/lib/gprim/geom/delete.c, src/lib/gprim/geom/draw.c, src/lib/gprim/geom/geomclass.h:
	Handle tagging of appearance and the necessary per-node data madness
	more efficiently (i.e. do _not_ allocate and check for per-node data
	if transparency is not enabled).

	* src/lib/mg/common/mgP.h: Cosmetics.

	* src/lib/shade/texture.c:
	TxMerge() did not correctly increase the ref.-count in all cases.

	* src/lib/oogl/util/ooglutil.h: Fix memory debug definitions.

	* src/lib/mg/common/mg.c:
	Don't forget to set ap->tx to NULL after calling TxDelete().

	* src/lib/geometry/transobj/transobj.c:
	TransStreamIn(): TransObjStreamIn() can (successfully) return with an
	empty handle, in which case we must not try to access the
	(non-existing) TransObj.

	* src/bin/geomview/common/comm.c: TransObj handling had a memory leak.

	* src/bin/NDview/Makefile.am, src/bin/crayola/Makefile.am, src/bin/labeler/Makefile.am, src/bin/ndutils/Makefile.am, geomview.sh:
	Adjust environment variables in preparation for Orrery and maniview
	autoconf revision.

	* configure.ac: Fix debug malloc definitions.

	* configure.ac, data/shaders/Makefile.am:
	Check for shader compilers sdrc (Pixie) and shaderdl
	(3Delight). Luckily Aqsis, Pixie and 3Delight produce shader files
	with different suffixes.

	* data/shaders/GVblendconstant.sl, data/shaders/GVblendplastic.sl, data/shaders/GVdecalconstant.sl, data/shaders/GVdecalplastic.sl, data/shaders/GVmodulateconstant.sl, data/shaders/GVmodulateplastic.sl, data/shaders/GVreplaceconstant.sl, data/shaders/GVreplaceplastic.sl:
	Use texture(..., "width", 0.0); at least aqsis otherwise produces
	textures which are just overblurred.

2007-03-19  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* doc/geomview.texi: Image object doc fixes.

	* src/lib/gprim/sphere/spherecreate.c:
	Typo (CR_SPHERETEX -> CR_SPHERETX)

	* src/lib/gprim/sphere/spherecreate.c: Undo previous commit.

	* src/lib/shade/image.c, src/lib/gprim/sphere/spherecreate.c:
	Fix handling of raw image data.

	* src/bin/geomutil/maple2oogl/README.gvplot, src/bin/geomutil/maple2oogl/gvplot.mapleV8, src/bin/geomutil/maple2oogl/gvplot.mws, src/bin/geomutil/maple2oogl/savegvplot.mws:
	Most documentation.

	* src/bin/geomview/common/drawer.h, src/bin/geomview/common/space.c, src/bin/geomview/common/transform.c, src/bin/geomview/common/transform.h, src/bin/geomview/common/drawer.c:
	ND-fixes.

2007-03-18  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	Support for textured spheres/define TxST structure + transforms,
	support for texture transform stacks.

	* src/bin/geomview/common/worldio.c: Comment/cosmetics.

	* Makefile.am: Use absolute path-names for build-dir geomview script.

2007-03-16  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/mg/opengl/mgopenglshade.c, src/lib/mg/ps/mgps.c, src/lib/mg/rib/mgrib.c, src/lib/mg/rib/mgribdraw.c, src/lib/mg/rib/mgribmesh.c, src/lib/mg/x11/mgx11.c, src/lib/mg/buf/mgbuf.c, src/lib/mg/common/mg.c, src/lib/mg/common/mg.h, src/lib/mg/common/mgP.h, src/lib/mg/opengl/mgopengl.c:
	Prepare for texture transform stacks to support texturing of objects
	pasted together via INSTs and TLists.

	* src/lib/gprim/sphere/spherecreate.c: Compilation fix.

	* src/lib/gprim/sphere/sphereP.h: Get rid of a compiler warning.

	* doc/version.texi: This file should not be kept in the CVS.

	* src/lib/gprim/sphere/spherecreate.c:
	Start defining texture transformations.

	* src/lib/gprim/sphere/sphere.h, src/lib/gprim/sphere/sphereP.h, src/lib/gprim/sphere/sphereclass.c, src/lib/gprim/sphere/spherecreate.c, configure.ac, src/lib/gprim/sphere/Makefile.am:
	Optionally use a polar mesh for drawing spheres, should also make it
	much easier to define spheres with textures.

	* src/lib/gprim/bezier/bezdice.c:
	BSP-tree invalidation now done via call-back.

	* src/lib/gprim/sphere/spheredice.c, src/lib/gprim/sphere/spheredraw.c:
	Initial revision.

	* src/lib/mg/rib/mgribdraw.c:
	Fix textured beziers (up-side down issue).

	* src/lib/gprim/bezier/bezdice.c: Cosmetics.

	* src/lib/mg/opengl/mgopenglmesh.c:
	Turn-off texturing before drawing edges, otherwise at least GL_REPLACE
	leads to the wrong colors (for the edges).

	* src/bin/geomview/common/drawer.c, src/bin/geomview/common/drawer.h, src/bin/geomview/common/event.c, src/bin/geomview/common/lights.c, src/bin/geomview/common/rman.c, src/bin/geomview/common/space.c, src/bin/geomview/common/transform.c, src/bin/geomview/common/transform.h, src/bin/geomview/common/ui.h, src/bin/geomview/common/worldio.c:
	Try to be a little bit more consistent in the choice of data-types in
	some places.

	* src/lib/gprim/bezier/bezbound.c:
	Fix bbox for pdim == 4 with 3d drawing.

	* src/lib/shade/texture.c, src/lib/shade/appearance.h:
	tex->background really is only RGB, _not_ RGBA (see glTexEnvf(3)).

	* src/lib/shade/apstream.c, src/lib/shade/light.c:
	Use 8 digits for output of float.

	* src/lib/mg/opengl/mgopenglshade.c:
	mgopengl_needtexture(): always load tex->tfm, even if the texture in
	the cache is otherwise identical to the desired texture.

	* src/lib/mg/common/mgtexture.c:
	mg_same_texture(): tex->background is only relevant for tex->apply == blend.

2007-03-15  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/gprim/sphere/spherecreate.c: Cosmetics.

	* src/lib/mg/rib/mgrib.c, src/lib/mg/rib/mgribdraw.c, src/lib/mg/rib/mgribmesh.c, src/lib/mg/rib/mgribshade.c, src/lib/mg/rib/mgribtoken.c, src/lib/mg/rib/mgribtoken.h:
	Debugging, correctly draw flat shaded stuff (i.e. emit per-vertex
	normals in this case). Shading logic was broken in mgribmesh.c and
	mgribdraw.c. Leave the texture clipping to RiMakeTexture(). Disable
	texture alpha-channel when transparency is not enabled (exception
	GL_BLEND, cause the the alpha channel of the texture only influences
	the colouring, not the transparency).

	* doc/version.texi: Update, this file does not belong to the CVS.

	* data/shaders/GVblendconstant.sl, data/shaders/GVblendplastic.sl, data/shaders/GVdecalconstant.sl, data/shaders/GVmodulateconstant.sl, data/shaders/GVmodulateplastic.sl, data/shaders/GVreplaceplastic.sl, data/shaders/Makefile.am:
	Shader debugging, should work now, more or less.

	* data/shaders/GVreplaceconst.sl, data/shaders/GVreplaceconstant.sl:
	Renamed.

	* src/lib/mg/rib/mgrib.c, src/lib/mg/rib/mgribshade.c, src/lib/mg/rib/mgribtoken.c, src/lib/mg/rib/mgribtoken.h:
	Further progress with texture and alpha-aware shaders.

	* doc/version.texi: Update. This file should not be in the  CVS.

	* data/shaders/GVblendplastic.sl, data/shaders/GVdecalplastic.sl, data/shaders/GVmodulateplastic.sl, data/shaders/GVreplaceplastic.sl:
	Fixed some silly bugs. We still need some shaders which ignore the
	alpha channel if transparency is enabled; or give all of them another
	float parameter which is used to switch off the alpha channel.

2007-03-14  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* configure.ac: Check for aqsl, the aqsis shader language compiler.

	* data/shaders/.cvsignore: Ignore Makefile.in.

	* data/Makefile.am:
	Conditionally compile shader sources for the Aqsis renderer.

	* data/shaders/Makefile.am:
	Initial revision; conditionally compile shader sources for the Aqsis
	renderer.

	* src/lib/gprim/geom/geomclass.h, src/lib/mg/opengl/mgopengldraw.c, src/lib/mg/opengl/mgopenglmesh.c:
	Also honor the alpha channel provided by the texture. Do some
	restructering of mgopengl_bsptreerecursive().

	* src/lib/shade/appearance.h: Comment stuff.

	* data/shaders/GVreplaceconst.sl, data/shaders/GVreplaceplastic.sl, data/shaders/GVblendconstant.sl, data/shaders/GVblendplastic.sl, data/shaders/GVdecalplastic.sl, data/shaders/GVmodulateconstant.sl, data/shaders/GVmodulateplastic.sl:
	Bring the stuff (hopefully) into accordance with the OpenGL docs
	(because this is what Geomview also uses).

	* src/bin/geomview/common/drawer.c, src/bin/geomview/common/transform.c:
	Hang the BSP-tree to dg->Lgeom, not dg->Item. Otherwise
	transformations would need special handling.

	* src/lib/mg/opengl/mgopenglP.h, src/lib/mg/opengl/mgopenglshade.c:
	Even for constantly shaded objects we should allow override of the
	alpha channel by material->diffuse[3]. Fix that.

	* src/lib/mg/opengl/mgopenglshade.c, src/lib/shade/appearance.h, src/lib/shade/texture.c:
	Implement "apply = replace" mode; texture color simply replaces the
	surface color.

	* data/shaders/rgbmaskpaintedconstant.sl, data/shaders/rgbmaskpaintedplastic.sl:
	Renamed

	* data/shaders/GVblendconstant.sl, data/shaders/GVblendplastic.sl, data/shaders/GVdecalconstant.sl, data/shaders/GVdecalplastic.sl, data/shaders/GVmodulateconstant.sl, data/shaders/GVmodulateplastic.sl:
	Initial revision.

	Texture stuff seems to work. We need some shaders to actually
	implement texturing the same way as the OpenGL backend is doing it.

	* src/lib/mg/buf/mgbuf.c, src/lib/mg/common/mg.c, src/lib/mg/common/mg.h, src/lib/mg/opengl/mgopengl.c, src/lib/mg/ps/mgps.c, src/lib/mg/x11/mgx11.c:
	mgctxset() has now a return value: -1 on error, 0 on success.

	* data/shaders/rgbapaintedconstant.sl, data/shaders/rgbmaskpaintedconstant.sl:
	Initial revision.

	* src/lib/mg/rib/mgrib.c: Comment.

	* doc/version.texi: Update. This file should not be in the CVS.

	* configure.ac: Provide PATH_MAX.

	* src/lib/mg/rib/mgrib.c, src/lib/mg/rib/mgribP.h, src/lib/mg/rib/mgribshade.c, src/lib/mg/rib/mgribtoken.c, src/lib/mg/rib/mgribtoken.h:
	Fiddle with texture stuff.

2007-03-12  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* configure.ac, doc/geomview.texi, src/bin/geomview/common/rman.c, src/lib/mg/rib/mgrib.c, src/lib/mg/rib/mgribP.h, src/lib/mg/rib/mgribdraw.c, src/lib/mg/rib/mgribmesh.c, src/lib/mg/rib/mgribshade.c, src/lib/mg/rib/mgribtoken.c, src/lib/mg/rib/mgribtoken.h:
	Substantial progress in supporting textures with RenderMan. Not really
	complete yet.

	* src/lib/shade/appearance.h, src/lib/shade/image.c:
	New function ImgWriteFilter() to dump the image to disk through an
	external filter program (i.e. convert to tiff for RenderMan texture
	support).

	* configure.ac:
	Check for pamtotiff in anticipation of RenderMan texture support.

	* src/lib/shade/appearance.h, src/lib/shade/image.c:
	New globally defined functions ImgWritePGM() and ImgWritePNM(), in
	preparation for real RenderMan texture support.

	* doc/version.texi: Update.

	* src/lib/shade/image.c: Sanity checks for write_pmm/pgm.

2007-03-11  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/mg/rib/mgribmesh.c, src/lib/mg/rib/mgrib.c:
	Fix the (rudimentory) texture support. This really needs to be reworked.

	* src/lib/gprim/list/liststream.c:
	ListStreamOut(): Proper indent of inferior geometries.

	* src/lib/shade/image.c:
	Continue parsing, even if reading of specific channels fails. This
	increases the chance of skipping over broken  binary data.

	* src/bin/geomview/common/worldio.c, src/lib/camera/camstream.c, src/lib/geometry/ntransobj/ntransobj.c, src/lib/geometry/transobj/transobj.c, src/lib/gprim/geom/geomstream.c, src/lib/gprim/inst/inststream.c, src/lib/gprim/list/listdraw.c, src/lib/gprim/list/liststream.c, src/lib/oogl/refcomm/handle.c, src/lib/oogl/refcomm/handle.h, src/lib/oogl/refcomm/handleP.h, src/lib/oogl/refcomm/streampool.c, src/lib/oogl/refcomm/streampool.h, src/lib/shade/appearance.c, src/lib/shade/appearance.h, src/lib/shade/apstream.c, src/lib/shade/image.c, src/lib/shade/light.c, src/lib/shade/material.c, src/lib/shade/texture.c:
	Dump handles as handles if possible (but take care to dump every
	referenced object also). ppath fix for lists. Formatting of
	StreamOut() (proper -- or at least better -- indentation where
	possible).

	* doc/geomview.texi:
	Bring command line switches in sync with the stuff acutally supported,
	add some notes about translucency.

	* src/lib/gprim/inst/instmisc.c:
	No need to free bsptree->tree when transforming an INST.

	* src/lib/gprim/geom/bsptreeP.h:
	Delete the no longer needed structure component geomflags.

	* src/bin/geomview/geomview.1:
	Move -noopengl explanation closer to the other "-no..." options.

	* doc/geomview.texi, doc/version.texi: Document new image OOGL object.

2007-03-10  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/gprim/geom/draw.c: Undo faulty optimizations. Gnah.

	* src/lib/gprim/geom/geomclass.h:
	Protect GeomNodeDataByPath() and GeomNodeDataCreate() against an
	undefined (NULL) object path.

	* src/lib/camera/camera.c: Use the same bgcolor default as the GUI.

	* src/bin/geomview/common/main.c:
	Use 1.0/3.0 and leave it to the comiler to generate the best
	approximation ...

	* doc/geomview.texi, doc/version.texi: Start update of docs.

	* src/lib/shade/texture.c, src/lib/window/winstream.c, src/bin/geomview/common/comm.c, src/bin/geomview/common/lang.c, src/lib/gprim/bezier/bezdice.c, src/lib/gprim/geom/draw.c, src/lib/gprim/geom/geomclass.h, src/lib/gprim/mesh/meshdraw.c, src/lib/gprim/ndmesh/ndmeshdraw.c, src/lib/gprim/npolylist/npldraw.c, src/lib/gprim/quad/quaddraw.c, src/lib/shade/image.c:
	Get rid of some compiler warnings.

	* doc/Makefile.am: Install man-pages.

	* src/lib/gprim/geom/bsptree.c, src/lib/gprim/geom/draw.c:
	Tagged appearance logic was somewhat broken.

	* doc/Makefile.am: Remove geomview.1, oogl.5.man and geomview.5.man.

	* doc/geomview.1: generated from (and in) src/bin/geomview/

	* doc/oogl.5.man: Just a duplicate of oogl.5

	* doc/geomview.5.man: Just a duplicate of geomview.5

	* src/bin/geomview/x11/gvcamui.c:
	ui_ppmglxsnapshot(): get rid of some unused variables.

	* src/lib/camera/camstream.c, src/lib/gprim/geom/geomstream.c, src/lib/window/winstream.c:
	Cleanup and unification w.r.t. to Handles; applies also to all other
	xxxStreamIn() routines.

	* src/lib/camera/camera.c:
	Handle handling cleanup, was maybe unnecessary, but the current code works.

	Also:

	A camera now (optionally) has a background image and a background
	color. IMHO those things do not belong to the mg-layer. It is
	questionabble, though, whether stuff like this belongs to the camera.

	* src/lib/camera/camera.h: New atributes:

	CAM_BGCOLOR, CAM_BGIMAGE, CAM_BGIMGHANDLE.

	A camera now (optionally) has a background image and a background
	color. IMHO those things do not belong to the mg-layer. It is
	questionabble, though, whether stuff like this belongs to the camera.

	* src/lib/camera/cameraP.h:
	A camera now (optionally) has a background image and a background
	color. IMHO those things do not belong to the mg-layer. It is
	questionabble, though, whether stuff like this belongs to the camera.

	* src/lib/window/window.c:
	Ref->handle has been replaced by a list of handles and is properly
	handled in RefInit() now.

	* src/lib/window/windowP.h: Get rid of the silly "long" data type.

	* src/lib/gprim/inst/instdraw.c, src/lib/gprim/list/listdraw.c, src/lib/gprim/mesh/meshdraw.c, src/lib/gprim/ndmesh/ndmeshdraw.c, src/lib/gprim/npolylist/npldraw.c, src/lib/gprim/polylist/pldraw.c, src/lib/gprim/quad/quaddraw.c:
	BSP-tree cleanup: properly handle the case that a geometry can belong
	to several nodes in the object hierarchy (referenced through handles).

	* src/lib/gprim/bezier/bezcreate.c, src/lib/gprim/bezier/bezdice.c, src/lib/gprim/bezier/bezdraw.c, src/lib/gprim/bezier/bezierP.h:
	Use a Handle to define callbacks for invalidating BSP-trees. The issue
	is that a geometry can belong to several nodes in the object hierarchy
	when it is referenced by handles, and hence can belong to several
	BSP-trees, and may have to be entered more than once to the same
	BSP-tree (with a different position or appearance).

	* src/lib/gprim/inst/instP.h, src/lib/gprim/inst/instcreate.c, src/lib/gprim/inst/inststream.c, src/lib/gprim/list/listP.h, src/lib/gprim/list/listcreate.c, src/lib/gprim/list/liststream.c:
	BSP-tree cleanup: can now live again with the standard HandleUpdRef()
	callback.

	* src/lib/gprim/inst/instmisc.c:
	Transform[To](): installed a 3d transform now leaves any ND-transform
	alone and vice-versa. Needed to allow for simplification in the
	top-level ND-drawing code in
	really_draw_view()@src/bin/geomview/common/drawer.c

	* src/lib/gprim/polylist/plcreate.c:
	PolyListCreate(): always delete the temporary projected polylist used
	to speed up ND-drawing.

	* src/lib/gprim/polylist/plcopy.c, src/lib/gprim/polylist/plload.c, src/lib/gprim/polylist/polylistP.h:
	ND-drawing: allocate on demand an additional polylist; it is not
	necessary and inefficient to copy over the structure of the polylist
	on every draw. This way it has to be done only once.

	* src/lib/gprim/polylist/plsphere.c:
	Treat VERT_4D pl's as projective things in 3d.

	* src/lib/gprim/mesh/meshcreate.c, src/lib/gprim/ndmesh/ndmeshcreate.c, src/lib/gprim/npolylist/nplcreate.c, src/lib/gprim/polylist/plcreate.c:
	BSPTree alloc/dealloc is done at a higher level now.

	* src/lib/gprim/mesh/meshcopy.c: Ansification.

	* src/bin/geomview/common/worldio.c, src/bin/geomview/common/space.c:
	Cosmetics.

	* src/bin/geomview/common/main.c:
	Remove unnecessary handle ops external declaration.

	* src/bin/geomview/common/comm.c:
	Image and appearance objects. Handle ref-count related fixes.

	* src/bin/geomview/common/lang.c, src/bin/geomview/common/lang.h, src/bin/geomview/common/lispext.c, src/bin/geomview/common/lispext.h:
	Image and appearance objects.

	* src/bin/geomview/common/drawer.c, src/bin/geomview/common/drawer.h, src/bin/geomview/common/ndshade.c, src/bin/geomview/common/transform.c:
	internal ND-view simplification

	* src/lib/gprim/geom/bsptree.c, src/lib/gprim/geom/bsptree.h, src/lib/gprim/geom/bsptreeP.h, src/lib/gprim/geom/copy.c, src/lib/gprim/geom/create.c, src/lib/gprim/geom/delete.c, src/lib/gprim/geom/draw.c, src/lib/gprim/geom/geom.h, src/lib/gprim/geom/geomclass.h:
	BSP-tree stuff was broken: as geometries can be referenced by handles
	we need to take special precaution when attaching global data to geoms.

	* src/lib/oogl/util/Makefile.am, src/lib/oogl/util/Headers:
	Add dbllist.h header.

	* src/lib/oogl/util/ppopen.c: Program flow logic was broken. Fix that.

	* src/lib/oogl/util/create.h: Delete unused CR_HANDLE attribute.

	* src/lib/shade/Makefile.am, src/lib/shade/appearance.c, src/lib/shade/appearance.h, src/lib/shade/apstream.c:
	Strip off texture and material stuff. Allow defining global handles
	for appearances.

	* src/lib/geometry/ntransobj/ntransobj.c, src/lib/geometry/ntransobj/ntransobj.h, src/lib/geometry/transobj/transobj.c, src/lib/geometry/transobj/transobj.h, src/lib/oogl/refcomm/Makefile.am, src/lib/oogl/refcomm/handle.c, src/lib/oogl/refcomm/handle.h, src/lib/oogl/refcomm/handleP.h, src/lib/oogl/refcomm/reference.c, src/lib/oogl/refcomm/reference.h, src/lib/oogl/refcomm/streampool.c, src/lib/oogl/refcomm/streampool.h:
	Fix the deeply broken handle reference count stuff. Gnah.

	* src/lib/geometry/transform3/transform3.h: Cosmetics.

2007-03-09  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/gprim/bezier/bezbound.c, src/lib/gprim/inst/instbound.c, src/lib/gprim/mesh/meshbound.c, src/lib/gprim/polylist/plbound.c, src/lib/gprim/quad/quadbound.c, src/lib/gprim/skel/skelbound.c, src/lib/gprim/vect/vectbound.c:
	Handle VERT_4D co-ordinates as homogeneous coords if no ND-transform is given.

	* src/lib/mg/buf/mgbufdraw.c, src/lib/mg/ps/mgpsdraw.c, src/lib/mg/x11/mgx11draw.c:
	Copy with numerical instabilities which everting normals.

	* src/lib/mg/common/mg.h:
	Add a pointer to the current BSP-tree to mgNDctx, part of a larger
	BSP-tree cleanup.

	* src/lib/mg/rib/mgrib.c, src/lib/mg/x11/mgx11.c, src/lib/mg/buf/mgbuf.c:
	Return the new ap. There is just no point in returning the user
	specified ap pointer.

	* src/lib/gprim/comment/commentstream.c:
	Get rid of just another memory leak.

	* src/lib/gprim/comment/commentcreate.c: Cosmetics.

	* src/lib/geometry/transform3/tm3print.c: Change the output format.

	* src/lib/geometry/transformn/transformn.h:
	Slight changes, typos mostly.

	* src/lib/geometry/hpointn/hpointn.h: Typo.

	* src/lib/geometry/hpoint3/hpoint3.h:
	Support for denormalized linear combination.

	* src/lib/Makefile.am: link (optionally) with libz

	* configure.ac:
	false/true/bool definition. Also (optionally) check for zlib/bzlib.

	* src/lib/oogl/util/malloc-debug.c: Fix alloc size accounting.

	* src/lib/oogl/util/iobfutil.c, src/lib/oogl/util/iobuffer.h:
	Fix iobfcontext(); syntax error messages should work again now.

	* src/lib/shade/image.c, src/lib/shade/material.c, src/lib/shade/texture.c, src/lib/oogl/util/dbllist.h:
	Initial revision.

2007-02-19  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/mg/common/mgtexture.c: Add pngtopnm filter.

2007-02-17  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/mg/opengl/mgopengldraw.c:
	Merge Adrian Rossiter's changes for concave and self-intersecting polygons.

2007-02-16  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/mg/opengl/mgopenglshade.c, src/lib/mg/opengl/mgopengl.c, src/lib/mg/opengl/mgopengldraw.c:
	Fix logic concerning alpha blending.

	* src/lib/gprim/inst/instdraw.c: BSP-tree fixes.

	* src/lib/gprim/ndmesh/ndmeshdraw.c, src/lib/gprim/npolylist/npldraw.c, src/lib/gprim/polylist/pldraw.c, src/lib/gprim/quad/quaddraw.c, src/lib/gprim/geom/bsptree.c, src/lib/gprim/geom/bsptreeP.h, src/lib/gprim/mesh/meshdraw.c:
	Change BSPTreePushAppearance(): appearances are only set when
	geom->ap_tagged != NULL.

	* src/lib/mg/common/mgtexture.c: Remove a crazy comment.

	* src/lib/shade/appearance.c:
	TxStreamOut(): fix file: -> alphafile bug.

	* src/bin/geomview/x11/gvcamui.c:
	Some cleanup w.r.t. to the logic of gv_no_opengl and the pre-processor
	symbols MGGL, MGOPENGL and MGX11. Also, `#define' gv_no_opengl to
	`true' if !(MGGL || MGOPENGL) to simplify some of the
	gv_no_opengl/MG...  related conditionals.

	* src/lib/mg/common/mg.c:
	mg_untagappearance(): Only delete texture and light if the appearance
	slot is not currently in use; delete astk->texture, not
	ctx->astk->texture (copy and paste bug).

	* src/bin/geomview/x11/gvcamui.c:
	Remove and/or document some slightly confusing preprocessor constructs.

	* src/lib/gprim/inst/instdraw.c:
	Fix a BSP-tree related bug: do not loop over the transformation if
	when not adding to the tree, but just distributing the tree-handle to
	all sub-geometries (when running InstBSPTree(..., action =
	BSPTREE_CREATE), in contrast to action == BSPTREE_ADDGEOM).

	* configure.ac:
	Disable OSMesa because it just does not work, unluckily.

2007-02-15  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/mg/common/mgtexture.c:
	Support bzip2 for compression of texture files.

	* src/bin/NDview/NDdemo, src/bin/NDview/NDview:
	Remove invalid script interpreter

	* configure.ac: Get rid of the CONFIG_SUBDIR stuff.

	* configure.ac, src/bin/geomview/x11/gvcamui.c, src/bin/geomview/x11/gvsave.c, src/bin/geomview/x11/interface/Save.mib:
	Implement a GLX off-screen snapshot by rendering into a GLX
	pixmap. The idea is that off-screen rendering does not suffer from
	partially obscured windows, screen-saver etc.

	* configure.ac:
	Gnah. Should read twice through my changes before committing.

	* configure.ac:
	Should check for glXAllocateMemoryMESA() not GLX_MESA_allocate_memory.

	* configure.ac, src/bin/geomview/x11/gvcamui.c, src/bin/geomview/x11/gvsave.c, src/bin/geomview/x11/interface/Save.mib:
	Check for libOSMesa if we are using Mesa and re-enable
	ppmmesasnapshot() in gvcamui.c

2007-02-14  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/oogl/wa/wa.lex.c, src/lib/oogl/wa/wa.yacc.c, src/lib/oogl/wa/wa.yacc.h:
	Auto-generated.

	* src/lib/oogl/wa/Makefile.am:
	Split-out rule for lex.yy.c, otherwise a dependency for "all:" cannot
	be resolved.

	* src/bin/geomview/common/main.c, src/bin/geomview/common/main.h, src/bin/geomview/geomview.1, src/bin/geomview/x11/gvcamui.c, src/bin/geomview/x11/gvmain.c:
	Implement a -noopengl option.

	* Makefile.am, geomview.sh:
	--print-BLAH switches to figure out the location of the data directory
	etc. of an already installed geomview.

	* src/lib/mg/common/mgtexture.c: Cosmetics.

2007-02-13  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/gprim/geom/geomstream.c:
	Get rid of the infamous "can't seek back for enough (on pipe?)" error
	message because it is no longer adequate and misleading.

	* src/lib/mg/rib/mgribdraw.c: Cosmetics.

	* src/lib/mg/opengl/mgopenglshade.c:
	Do the obvious fixes for tex_adequate().

	* src/lib/mg/opengl/mgopengldraw.c:
	Fix texture handling during BSP-tree traversal.

	* doc/version.texi, doc/geomview.texi:

	Handle NormalTransform() correctly.

	Invalidate the BSP-tree if any object underlying a handle changes.

	* src/lib/gprim/geom/bsptree.c, src/lib/gprim/geom/bsptreeP.h:
	Handle NormalTransform() correctly (i.e. use the dual of T).

	* src/lib/gprim/geom/replace.c: Call BSPTreeFreeTree().

	* src/lib/gprim/bezier/bezdraw.c: Cleanup.

	* src/lib/geometry/transobj/transobj.c, src/lib/geometry/transform3/tm3adjoint.c, src/lib/geometry/transform3/tm3dual.c, src/lib/geometry/transform3/tm3invert.c:
	Cosmetics.

	* src/lib/geometry/point3/point3.h:
	Simplify NormalTransform(), add a comment stating that
	NormalTransform(Tdual, ...) should be called with the dual of T.

	* src/lib/geometry/ntransobj/ntransobj.c: Cosmetics.

2007-02-12  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	Move deletion of BSP-trees to GeomDelete().

2007-02-10  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* m4/lf_local.m4:
	Hopefully LF_LINK_HEADERS() works _NOW_ for in-path and VPATH builds.

	* m4/lf_local.m4: Undo a bug introduced previously by myself.

2007-02-09  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	Implement BSP-tree stuff for ND objects. Not tested. Needs testing.

	* src/lib/gprim/mesh/meshcreate.c: nu*nv, not nu+nv, fixing myself.

	* src/bin/geomview/common/drawer.c:
	Give every object accesible through the browser a
	BSP-tree. Transluceny is now correctly implemented for OpenGL (and
	RMAN, of course, as RMAN handles translucency by itself). Supported is
	a single translucent compound object (like the list of SaVI's coverage
	cones) which is drawn on a solid scene consisting of arbitrarily many
	objects.

	* src/bin/geomview/common/rman.c, src/bin/geomview/common/worldio.c:
	Small changes w.r.t. to unneeded (?FIXME) appearance copies

	Support BSP-trees consisting of multiple geoms.

	* src/lib/gprim/skel/skelP.h, src/lib/gprim/skel/skelbound.c, src/lib/gprim/skel/skelpick.c:
	Pick support for SKEL, just clone the vect code (skelpick.c contains a
	code fragment which seemingly was meant as a draft; however, the VECT
	code works and really just naturally carries "itself" over to the SKEL
	case).

	The "origin/bbox-center" keyword to transform and transform-incr was a
	bad idea. There is still a new button in the Tools-menu which
	translates the CENTER object to the currently selected geom's bounding box.

	* src/bin/geomview/common/comm.c:
	Document ntransform keyword in online-help for (read ...) command.

	* src/lib/gprim/inst/instcreate.c, src/lib/gprim/inst/inststream.c:
	HandleRegister() needs &inst->NDaxis, not inst->NDaxis, otherwise
	inst->NDaxis (originally NULL) cannot be modified.

	(i.e. LOCAL) with ND-drawing.

	Fixed a BUNCH of memory leaks and other errors. But the main-work was
	to move thehomogeneous component to index 0. And the most important
	change was that each camera of an ND-cluster now has additionally its
	own 3d transform.

	* src/bin/gvclock/gvclock.in:
	Calling convention for transfrom-incr has changed (will undo that later).

	* src/bin/geomview/common/drawer.c, src/bin/geomview/common/lispext.c, src/bin/geomview/common/ndshade.c, src/bin/geomview/common/space.c, src/bin/geomview/common/transform.c:

	The homoegenous component for ND is now at index 0. VERT_4D flag is
	now only a mere input-flag for ND. Fixed several bugs. Forgot about
	the rest. (but the damn thing seems to work).

	* src/lib/geometry/hpoint3/hpoint3.c, src/lib/geometry/hpoint3/hpoint3.h, src/lib/geometry/hpoint3/hpoint3b.c:
	Some more utility functions concerning the conversion between

	HPt3Normalize() is dead, changed everything to HPt3Dehomogenize.

	* src/lib/geometry/transformn/tmNpolardecomp.c, src/lib/geometry/transformn/transformn.c, src/lib/geometry/transformn/transformn.h:

	Optionally change the active camera only on focus-change events; this
	is most desirable in the context of multiple windows when it starts to
	become complicated to move the mouse cursor back to the tool panel
	without crossing another camera window.

	* src/lib/oogl/lisp/lisp.c:
	Fix a severe memory leak in AssignArgs(): if the argument type is
	LLOBJECT and the argument itself is either not a list or the LHOLD
	modifyer is in effect, then the ref-count of the object would be
	increased one times too often which had the effect that constructs
	like (e.g.)

	(if (real-id blah) (echo foo) (echo bar))

	would not free there arguments lists. Very bad.

2006-10-22  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/bin/geomview/common/drawer.c: Correct drawing of ND cameras.

	* src/bin/geomview/common/worldio.c:
	lisp function (camera-prop ...): handle keyword args correctly,
	including checking for the correct keyword.

	* src/bin/geomview/common/ui.h: Cosmetics.

	* src/bin/geomview/common/transform.c:
	drawer_transform(): now returns success status.

	* src/bin/geomview/common/space.c: Unused variable compile warning.

	* src/bin/geomview/common/ndshade.c:
	Account for changes in mgNDctx struct.

	* src/bin/geomview/common/lang.h: Remove comma at end of enum.

	* src/bin/geomview/x11/gvui.h:
	Proto-type for ui_tool_center_origin_set() (to get rid of a compiler
	warning).

	* src/lib/geometry/hpointn/hpointnb.c, src/lib/geometry/transformn/transformn.c, src/lib/geometry/transformn/transformn.h:
	Do not use "short" for parameters; that doesn't make too much
	sense. New function TmNPermute() which applies a permutations to an
	ND-Transform (to map an x,y,z 3d sub-space to some other
	3d-subspace). Some more fixes w.r.t. to prolongation and restriction of ND vectors/matrices.

	* src/lib/gprim/inst/instdraw.c:
	Better handling of ND-drawing; also: support non-local locations with
	ND-drawing. Non-local origins, however, are not (and probably will not
	be) supported with ND-drawing.

	* src/lib/gprim/inst/instmisc.c: Cosmetics.

	* src/lib/geometry/ntransobj/ntransobj.c: Remove unused variables.

	* src/lib/gprim/tlist/tlist.h, src/lib/gprim/tlist/tltransform.c:
	Handle TransformN argument to TListTransform().

	* src/lib/gprim/vect/vectdraw.c:
	Fix ND drawing of VECTs: use the VECTs colors of no ND cmap is defined
	(same handling as in SKEL).

	* src/lib/mg/common/mg.h:
	restructured mgNDctx struct and hook functions; we can now push a
	3-Transform (make INST support much easier).

	* src/lib/mg/common/mg.c, src/lib/mg/common/mgP.h:
	mgc->T4 and associated 3To4() stuff has gone because it was unused;
	seems to be a relict of beginning ND-support.

	* src/lib/oogl/lisp/lisp.c:
	include ctype.h, fix compiler warning in print_help_formatted().

2006-10-20  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/oogl/util/create.h:
	New define CR_NCENTER to retrieve the center of a bounding box with
	GeomGet(bbox, ...)

	* src/bin/geomview/x11/gvcredits.c, src/bin/geomview/x11/gvfiles.c, src/bin/geomview/x11/gvlights.c, src/bin/geomview/x11/gvload.c, src/bin/geomview/x11/gvmaterial.c, src/bin/geomview/x11/gvmnpanel.c, src/bin/geomview/x11/gvsave.c, src/bin/geomview/x11/gvtoolui.c, src/bin/geomview/x11/gvui.c, src/bin/geomview/x11/gvui.h, src/bin/geomview/x11/interface/Tool.mib, src/bin/geomview/common/drawer.c, src/bin/geomview/common/drawer.h, src/bin/geomview/common/motion.c, src/bin/geomview/common/transform.c, src/bin/geomview/common/transform.h, src/bin/geomview/common/ui.c, src/bin/geomview/common/ui.h, src/bin/geomview/x11/gvappear.c, src/bin/geomview/x11/gvcameras.c, src/bin/geomview/x11/gvcolor.c, src/bin/geomview/x11/gvcommands.c:
	New toggle "Origin BBox": if set and a geometry is the center of
	motion (except the world), then the center of the geometry's bounding
	box is used as origin of the coordinate system (instead of just using
	the origin of the center-object's co-ordinate system).

	The idea is that this makes it much easier to look at objects which
	are translated out of the center of their own coordinate frame,
	e.g. by using an INST geometry.

	* src/bin/geomview/common/lang.c, src/bin/geomview/common/lang.h, src/bin/geomview/common/lispext.c, src/bin/geomview/common/lispext.h:
	The list of keyword names is now generated on the fly in
	define_keyword().

	* src/lib/gprim/bbox/bboxP.h, src/lib/gprim/bbox/bboxclass.c, src/lib/gprim/bbox/bboxcreate.c:
	CR_4MIN/4MAX do not cause VERT_4D to be set (why should), but simply
	install an HPoint3. Bounding boxes now compute their center point, it
	can be fetched from the bounding box via GeomGet(bbox,
	CR_CENTER/CR_NCENTER, &point) to retrieve the center as HPoint3 or HPointN.

	* src/lib/gprim/bbox/bboxbound.c, src/lib/gprim/bbox/bboxunion.c:
	Use CR_4MIN/4MAX.

	* src/lib/oogl/lisp/lisp.c:
	Automatically format the help text to be indented by 8 chars, and
	wrapped at column 72. This simplifies modifying help texts (no need to
	format manually). A double \n\n is interpreted as paragraph, all other
	embedded spaces, tabs and newlines are converted to a single space.

	* src/lib/gprim/bezier/bezbound.c, src/lib/gprim/mesh/meshbound.c, src/lib/gprim/ndmesh/ndmeshbound.c, src/lib/gprim/npolylist/nplbound.c, src/lib/gprim/polylist/plbound.c, src/lib/gprim/quad/quadbound.c, src/lib/gprim/skel/skelbound.c, src/lib/gprim/vect/vectbound.c:
	Use CR_4MIN/4MAX to generate the bounding box. VERT_4D can be set
	separately via CR_4D.

2006-10-19  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/gprim/inst/instbound.c: Typo.

	* src/bin/NDview/ndview.c, src/bin/ndutils/ColorPoint.c, src/bin/ndutils/GeExDir.c, src/bin/ndutils/slicer.c, src/bin/ndutils/snapshot.c, src/lib/geometry/ntransobj/ntransobj.c, src/lib/geometry/transformn/transformn.c, src/lib/geometry/transformn/transformn.h:
	Prepare for binary ntransform format.

	ND-INST support (origin and location local only, no multi-transform
	stuff, i.e. there are no NTLISTs).

	* src/lib/gprim/inst/inststream.c:
	The attempt to introduce ND-INSTs broke saving of the transformation
	matrix (axis), fix that.

	* src/lib/gprim/vect/vectbound.c: Fogot to intialize "min".

	* src/lib/gprim/vect/vectload.c: Initialize flag to 0.

	* src/lib/gprim/ndmesh/ndmeshbound.c, src/lib/gprim/npolylist/nplbound.c, src/lib/gprim/skel/skelbound.c:
	Fix previously introduced ND-bug.

	* src/lib/gprim/geom/create.c: GeomInit(): set pdim to 4 by default.

	* src/lib/gprim/bbox/bboxcenter.c, src/lib/gprim/bbox/bboxunion.c:
	Fix bugs previously introduced by my ND-changes.

	* src/lib/gprim/bbox/bboxbound.c: Some ND fixes.

	* src/lib/gprim/sphere/spherecreate.c:
	Fix a long-standing memory leakage bug: a sphere's Bezier-mesh and
	tlist were NEVER freed.

	* src/bin/geomview/common/transform.c:
	id_bsphere(): fix a memory leak (ND-case).

	* src/lib/gprim/geom/boundsphere.c: Fix a memory leak (ND-case).

2006-10-16  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/gprim/inst/instcreate.c, src/lib/gprim/sphere/spherecreate.c:
	Forgot the initialization of inst->ndaxis in some places.

	* src/bin/geomview/common/transform.c: Forgot yet another TmNDelete()

	* src/lib/gprim/inst/instP.h, src/lib/gprim/inst/instcreate.c, src/lib/gprim/inst/instmisc.c, src/lib/gprim/inst/inststream.c:

2006-10-15  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/bin/geomview/common/comm.c, src/bin/geomview/common/comm.h, src/bin/geomview/common/lang.c, src/bin/geomview/common/lang.h, src/bin/geomview/common/lispext.c, src/bin/geomview/common/worldio.c:
	Support ntransform as real lisp-object.

	look-recenter: only set the 3d transform if ND-viewing is NOT enabled.

	* src/lib/geometry/Makefile.am: Add ntransobj/ subdir.

	* configure.ac: Add src/lib/geometry/ntransobj/Makefile

	* src/lib/geometry/ntransobj/.cvsignore, src/lib/geometry/ntransobj/Headers, src/lib/geometry/ntransobj/Makefile.am, src/lib/geometry/ntransobj/ntransobj.c, src/lib/geometry/ntransobj/ntransobj.h:
	Initial revision.

	* src/bin/geomview/common/transform.c:
	apply_ND_transform(): need to delete Tmp, drawer_set_ND_xform() just
	makes a copy.

	* src/lib/gprim/sphere/spheremisc.c:
	Fix off-by-one loop-count errors in SphereEncompassXXXN().

	* src/lib/gprim/npolylist/nplsphere.c:
	Fix silly typos and complete the implementation (stopped somewhere in
	middle, unnoticed because the file was never compiled).

	* src/lib/gprim/npolylist/npolylistP.h:
	Proto-type for NPolyListSphere().

	* src/lib/gprim/npolylist/Makefile.am: Forgot to add nplsphere.c

	* src/lib/gprim/ndmesh/ndmeshclass.c, src/lib/gprim/npolylist/nplclass.c, src/lib/gprim/skel/skelP.h, src/lib/gprim/skel/skelclass.c:
	Do not forget to install BoundSphere() method.

	* src/lib/gprim/mesh/meshclass.c, src/lib/gprim/polylist/plclass.c:
	Cosmetics.

	* src/lib/gprim/geom/boundsphere.c:
	GeomBoundSphereFromBBox(): handle ND-BBoxes correctly.

	* src/bin/geomview/common/drawer.c, src/bin/geomview/common/drawer.h, src/bin/geomview/common/space.c, src/bin/geomview/common/transform.c:
	ND-stuff cleanup: just use the cameras C2W and W2C instead of using

	Quite a lot of ND drawing changes:

	look-encompass/-recenter etc. should work now; every camera of an
	ND-cluster now additionally has a 3d transform attached which acts on
	the 3d sub-space it is looking at; this is used by look-encompass. The
	prevous ND paradigm focal-len == translation in z direction was just
	an ugly hack.

	Motions are not applied to the 3d transforms while in Nd mode.

	Mouse-scaling now works while in Nd-mode, however, it is no longer
	treated as a motion: mouse initiated scaling in Nd is never
	incremental; changing this would require quite some more changes.

	Picking still does not work in Nd.

	Nd drawing honours the 3d transformations set by the xform/xform-set
	commands. But the result may look very funny.

	* src/bin/geomutil/hvectext/Makefile.am: Fix all-local: rule.

	* src/bin/NDview/NDview:
	Disable normalization, do not disable bboxes, they work in Nd now.

	* src/lib/oogl/wa/.cvsignore: Ignore some files.

2006-10-06  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	Use $(realpath ..) for the in-tree emodule definitions.

	* doc/version.texi: Update.

	* m4/lf_local.m4:
	Take relative/non relative source locations into account.

2006-10-04  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	Preparation for some ND-view changes; I plan support for working
	"look" and "positioning" commands. Needed quite some changes. I tagged
	everything with the GEOMVIEW_PRE_NDVIEW_CHANGE tag; so we can revert
	if it does not work out.

	* src/lib/mg/buf/mgbuf.c:
	Complete my previous fix concerning the orietation of "alien" objects.

2006-10-03  Mark Phillips  <mbp@geomtech.com>

	* doc/geomview.5, doc/geomview.5.man, doc/geomview.texi:
	add list of mode strings to documentation for event-mode gcl command

	* src/bin/geomview/x11/gvcamui.c:
	fixed snapshot setup code (used in ppmscreen snapshots) so that delay works on 64-bit systems

2006-10-03  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/mg/opengl/mgopengldraw.c:
	Applied Adrian Rossiter's fix for non-concave quadrilaterals.

	* src/lib/mg/buf/mgbuf.c:
	Flipping of the the coordinate system has to be done on a per-object
	basis because there are objects which do not belong to the world
	(e.g. SaVI's logo). This leaves, of course, room for optimization: as
	most objects belong to the world, we should flip the world's
	coordinate system (y-coordinate) and only do a per-object flipping for
	those few objects not belonging to the world.

	* src/lib/mg/x11/mgx11.c:
	Add a comment to some disabled code in mgx11_worldbegin().

	* src/bin/geomview/common/space.c:
	A more understandable help text for ND-xform.

	* src/bin/geomview/common/drawer.c:
	The previous code accessed components of obj after obj already had
	been deleted. Gnah. Buuh.

	* src/bin/geomview/common/comm.c: Cosmetics.

	* src/lib/oogl/lisp/lisp.c, src/lib/oogl/lisp/lisp2.h:
	"not", "or" and "and" functions.

	* data/NDview/scripts/4d.3wins, data/NDview/scripts/4d.4wins:
	Correct some more-or-LESS cosmetic errors.

2006-10-02  Lloyd Wood  <L.Wood@surrey.ac.uk>

	* ChangeLog:
	Correcting typo in my name. Plus expanding on doc/ build note.

2006-10-01  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/bin/geomview/x11/gvmnpanel.c, src/lib/mib/mibload.c:
	One of the more obscure features of the variable argument functions of
	the Xt toolkit is the handling of mnemonic's (in short keyboard
	short-cuts for menus etc): internally they are expected to be of type
	XID, which means "unsigned long int" outside of the X-server and
	CARD32 inside the X-server (we are talking about X-toolkits, and so we
	are outside the X-server and have "unsigned long int"). Now, at least
	on some 64bit archs passing 64bit variable arguments or 32bit variable
	arguments makes a difference.

	The solution is to use a type-cast to XID for mnemonic chars. This was
	the reason for the

	Warning:
	    Name: button_0
	    Class: XmCascadeButtonGadget
	    Illegal mnemonic character;  Could not convert X KEYSYM to a keycode

	messages received on (some, at least) 64bit systems.

	* src/bin/geomview/x11/gvmnpanel.c:
	Prevent automatic resizing of the main-panel; otherwise it will suffer
	an unnecessary change each a module is started.

2006-09-30  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* configure.ac, doc/version.texi: Bump version to post-rc9

	* ChangeLog: Update.

	* NEWS: Document the Nd-code bugfix.

	* configure.ac, doc/version.texi: Bump version to rc9.

	* src/bin/stereo/stereo.c: Fix unused variable warning.

	* src/lib/geometry/transformn/transformn.c, src/bin/geomview/common/drawer.c, src/bin/geomview/common/space.c, src/bin/geomview/common/transform.c:
	The nD stuff was really badly broken. I'm tempted to say that it did
	not have memory leaks, but _was_ one single big memory leak.

	* doc/version.texi: Update.

2006-09-30  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* rc9 checkpoint.

	* NEWS: Document the Nd-code bugfix.

	* configure.ac, doc/version.texi: Bump version to rc9.

	* src/bin/stereo/stereo.c: Fix unused variable warning.

	* src/lib/geometry/transformn/transformn.c, src/bin/geomview/common/drawer.c, src/bin/geomview/common/space.c, src/bin/geomview/common/transform.c:
	The nD stuff was really badly broken. I'm tempted to say that it did

	* doc/version.texi: Update.

2006-09-13  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* doc/geomview.texi:
	The menu entry for the GCL reference somehow vanished in the previous commit.

	* doc/version.texi: Update.

	* src/lib/gprim/comment/commentcreate.c:
	Undo a debugging relict that broke comment objects.

2006-08-30  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/gprim/vect/vectload.c: Typo.

	* doc/version.texi, doc/geomview.texi: Document binary SKEL format.

	* src/lib/gprim/skel/skelload.c: Binary SKEL format.

	* src/lib/gprim/npolylist/nplload.c: Fix Emacs per-file variable spec.

	* doc/version.texi: Update time-stamp.

2006-08-27  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* doc/version.texi, doc/geomview.texi:
	The node- and menu structure was partially garbled which confused the
	html output, at least. Get rid of most @ifFORMAT constructs; use
	@uref{} to refer to URL's (works nowadays).

	* src/lib/oogl/util/iobuffer.c: Debugging stuff.

2006-08-24  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* README.cvs:
	At least mention flex and bison (although the parser is now included
	in the CVS).

2006-08-23  Lloyd Wood  <L.Wood@surrey.ac.uk>

	* geomview.sh:
	This is the same Cygwin filesystem check that SaVi uses. It's less complex than
	if test "`uname | grep CYGWIN`"; then

	/cygdrive only exists if cygwin is running...

2006-08-21  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/oogl/wa/.cvsignore, src/lib/oogl/wa/wa.lex.c, src/lib/oogl/wa/wa.yacc.c, src/lib/oogl/wa/wa.yacc.h:
	Re-add scanner/parser output files.

2006-08-07  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* doc/version.texi: Update to post-rc8 version.

2006-08-07  Lloyd Wood  <L.Wood@surrey.ac.uk>

	* Makefile.am:
	Building doc/ at end -- so that if there's a problem with the tex or ps
	stuff, the C build has already completed and is unaffected.

	make geomview
	can be used if the C build has completed and the doc/ build fails,
	to create the ./geomview script than runs Geomview.

2006-08-07  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/bin/NDview/.cvsignore, src/bin/clipboard/.cvsignore, src/bin/cplxview/.cvsignore, src/bin/flythrough/.cvsignore, src/bin/ginsu/.cvsignore, src/bin/graffiti/.cvsignore, src/bin/hinge/.cvsignore, src/bin/ndutils/.cvsignore, src/bin/stereo/.cvsignore, src/bin/sweep/.cvsignore, src/bin/tackdown/.cvsignore, src/bin/transformer/.cvsignore:
	CVS ignore stuff.

	* src/lib/oogl/wa/Makefile.am:
	The dependency of the parser/scanner files should be on
	$(srcdir)/Makefile.in, not on Makefile.

	* src/lib/gprim/geom/geomstream.c: Remove a double file-close.

	* configure.ac: Use a fancy "post-rc8-CVS" version string.

	* src/lib/oogl/wa/.cvsignore: Ignore wa.yacc.c

	* doc/.cvsignore, doc/version.texi:
	Include version.texi into the CVS. IMHO this is a bad idea, but the
	maintainer-mode concept seems to be too complicated.

	* src/bin/NDview/.cvsignore, src/bin/clipboard/.cvsignore, src/bin/ndutils/.cvsignore:
	Ignore .deps directory.

	* configure.ac:
	Unconditionally check for ps2epsi, epstopdf, pdfimags and pnmtopng,
	even without MAINTAINERMODE:

	* reconf: Use "$@" not $* (expansion of arguments in quoted words).

2006-08-04  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* README.cvs, doc/Makefile.am, src/lib/oogl/lisp/Makefile.am, src/lib/oogl/wa/Makefile.am:
	Letting targets to create "maintainermode"-files depend on the
	automake-conditional MAINTAINERMODE was a very stupid idea.

2006-08-03  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* README.cvs: Mention that we need --enable-maintainer-mode ...

2006-08-02  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* NEWS: Meanwhile it's August 2006 ... tempus fugit.

	* ChangeLog: Update to 1.8.2-rc8 state.

	* configure.ac: Apply David's Darwin patch.

	* src/lib/mg/x11/mgx11.c, src/lib/mg/x11/mgx11windows.c:
	Quick and dirty hack to fix upside-down bug with MGX11 driver.

	* src/bin/labeler/Makefile.am:
	Fix the local (i.e. in build-tree) .geomview-labeler module def.

	* src/bin/geomview/common/transform.c:
	When doing "look-recenter" we do not want to apply the object
	transformation to the camera, because the object-trafo may contain
	arbitrary deformations (at least I do not like being deformed when
	watching Geomview). Instead, us a polar decomposition of the object's
	transform and apply only the orthogonal factor to the camera.

	* src/lib/Makefile.am:
	Maybe do not install the library if not using shared libraries (we do
	install ATM).

	* src/lib/oogl/wa/yystype.h, src/lib/oogl/wa/Headers, src/lib/oogl/wa/Makefile.am, src/lib/oogl/wa/fsaparse.l, src/lib/oogl/wa/fsaparse.y, src/lib/oogl/wa/wa.yystype.h:
	Renamed yystype.h to wa.yystype.h

	* src/lib/geometry/transform3/Makefile.am, src/lib/geometry/transform3/tm3polardecomp.c, src/lib/geometry/transform3/transform.h, src/lib/geometry/transform3/transform3.h:
	Polar decomposition of 3x3 matrix.

	* Makefile.am: Install non-private header-files in pkginclude.

	* configure.ac:
	Adapt xforms include and library paths to the xforms source distro at
	savannah.

	* src/lib/geometry/transform3/tm3polardecomp.c: Initial revision.

2006-08-01  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* configure.ac: Disable building a shared library by default.

	* src/lib/oogl/util/futil.c, src/lib/oogl/util/iobfutil.c:
	htons/l -> gv_htons/l (bug reported by David Morisson).

	Remove -rpath, not needed and not wanted by Debian.

2006-08-01  Steve M. Robbins  <steve@nyongwa.montreal.qc.ca>

	* src/bin/ChangeLog, src/bin/geomutil/plutil/offconsol.1:
	Fix manpage section.

	* ChangeLog, configure.ac, src/bin/ChangeLog, src/bin/stereo/stereo.c:
	Search for /usr/gfx/setmon at configure time; may be overridden by
	setting shell variable SETMON_PATH.  If not found, diagnostic is
	emitted at runtime by stereo.

	* src/lib/ChangeLog, src/lib/gprim/geom/knownclass.c:
	Fix bug in list of function prototypes, arising from the fact that the
	"*" in C attaches to the declarator rather than the type.

	* ChangeLog, geomview.sh:
	Specifying -help should only print help and not bring up geomview
	windows.  Fix diagnostic emitted when invoked with "-graphics" and no
	alternatives exist.

	* src/bin/ChangeLog, src/bin/example/oogl.c, src/bin/flythrough/main.c, src/bin/hinge/hui.c:
	Remove or rename function getline() to avoid clash with
	standard C library function.

	* src/lib/ChangeLog, src/lib/oogl/util/ooglutil.h:
	Remove duplicate declaration of fmemopen().

2006-07-31  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* configure.ac:
	AM_CONDITIONALS _must_ _not_ be defined conditionally. Gnah.

	* src/bin/Makefile.am:
	Forward the src_bin_module_subdirs to "make distclean" via distclean-local.

	* ChangeLog: *** empty log message ***

	* configure.ac:
	Search for GL/gl.h and GL/glx.h and make sure the beast still compiles
	without OpenGL.

	* geomview.sh:
	Set TCL/TK_LIBRARY variables on Cygwin, the Cygwin Tcl/Tk port is
	buggy in this respect.

	* src/bin/geomview/x11/gvcamui.c:
	Missing closing " after contact info update.

2006-07-30  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* configure.ac: Use PREFIX/share/geomview as data-dir (instead of
	PREFIX/share/geomview/data).

	* src/bin/ndutils/ColorPoint.c:
	Off-by-1 bug: in C (in contrast to maybe Fortran ...) the last array
	index is (size-1). Ups.

	* src/bin/ndutils/GeExDir.c: Debugging message.

	* src/bin/ndutils/slicer.c, src/bin/ndutils/snapshot.c:
	Consume the fourth number of the ND-axes command.

	* doc/geomview.texi, src/bin/geomview/common/space.c:
	The "ND-axes" command was not correctly documented: it accepts 4
	numbers, not 3, and return 4 numbers, not 3, when called without
	camera cluster ID. The last number seems to be hard-wired to -1. But???????

2006-07-31  Steve M. Robbins  <steve@nyongwa.montreal.qc.ca>

	* configure.ac: Search for /usr/gfx/setmon; may be overridden by
	setting shell variable SETMON_PATH.  Used in stereo module.

	* geomview.sh: Specifying -help should only print help and not
	bring up geomview windows.  Fix diagnostic emitted when invoked
	with "-graphics" and no alternatives exist.

2006-07-31  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* 1.8.2-rc7 release.

	* configure.ac:
	Search for GL/gl.h and GL/glx.h and make sure the beast still compiles
	without OpenGL.

	* geomview.sh:
	Set TCL/TK_LIBRARY variables on Cygwin, the Cygwin Tcl/Tk port is
	buggy in this respect.

	* src/bin/geomview/x11/gvcamui.c:
	Missing closing " after contact info update.

	The "ND-axes" command was not correctly documented: it accepts 4
	numbers, not 3, and return 4 numbers, not 3, when called without
	camera cluster ID. The last number seems to be hard-wired to -1. But???????

	* configure.ac, src/bin/Makefile.am:
	Cygwin (and maybe other non-Unix systems) do not have the
	Tcl_CreateFileHandler() function. Check for it and disable the crayola
	module if the function is not found.

	* src/bin/ndutils/clipoogl.c, src/bin/ndutils/slicer.c, src/bin/ndutils/wrappers.c, src/lib/mg/x11/mgx11draw.c, src/lib/mg/x11/mgx11windows.c:
	Remove some compiler warnings.

	* src/lib/oogl/lisp/Makefile.am:
	clisp.h must be copied to $(srcdir), otherwise the headers sym-link
	stuff does not work.

	* ChangeLog:
	Update email addresses; I need to be more careful to run rcs2log with
	the correct -u options.

	* doc/Makefile.am: Cleaned up as suggested by Steve M. Robbins.

	* data/Makefile.am: Erroneously included the groups/CVS/ subdir.

	* src/bin/gvclock/Makefile.am: CLEANFILES was set twice.

	* src/bin/sweep/.geomview-sweep, src/bin/tackdown/.geomview-tackdown, src/bin/transformer/.geomview-transformer, src/bin/hinge/.geomview-hinge, src/bin/stereo/.geomview-stereo, src/bin/graffiti/.geomview-graffiti, src/bin/flythrough/.geomview-flythrough, src/bin/ginsu/.geomview-ginsu, src/bin/cplxview/.geomview-cplxview:
	Generated by make

	* src/bin/geomview/common/comm.c:
	LDEFINE(read, ...): Fix a long standing memory bug;

	(read blah {stuff})

	treats blah just as keyword, the resulting lisp-object (e.g. a string
	"geometry") is never referenced again; so we _must_ free the keyword
	in this function, not only on error, but in any case.

	* src/lib/oogl/lisp/Makefile.am:
	clisp.h must be copied to $(srcdir), otherwise the headers sym-link
	stuff does not work.

	* ChangeLog:
	Update email addresses; I need to be more careful to run rcs2log with
	the correct -u options.

	* doc/Makefile.am: Cleaned up as suggested by Steve M. Robbins.

	* data/Makefile.am: Erroneously included the groups/CVS/ subdir.

	(read blah {stuff})

2006-07-26  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* AUTHORS, NEWS, README:
	Update some email addresses, time stamps, NEWs file.

2006-07-26  Lloyd Wood  <L.Wood@surrey.ac.uk>

	* INSTALL.Geomview:
	Pointing to Claus's new README.cvs textfile instead.

	* README: Updating credits list.

	* INSTALL.Geomview: Noting requirements for reconf to work.

	* reconf:
	Passing parameters through to the autoreconf command -- if reconf warns
	about --force to replace all files, saying reconf --force will do the expected thing.

2006-07-26  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/bin/Makefile.am: Fix handling of XFORMS_SUBDIRS.

2006-07-25  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* ChangeLog: Blah.

	* ChangeLog: *** empty log message ***

	* configure.ac: Bump version to 1.8.2-rc6

	* src/bin/Makefile.am:
	hinge, cplxview and flythrough need xforms, disable when xforms is not found.

2006-07-24  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* doc/Makefile.am:
	Don't include the PS version of the manual in the distro.

	* ChangeLog: Update.

	* configure.ac: Fogot to apply BE patch, bump version to rc5.

	* src/lib/oogl/util/futil.c, src/lib/oogl/util/iobfutil.c:
	Finally apply _AND_ commit (!) Rex Dieter's patch.

	* src/bin/stereo/stereo.c:
	Use PoolInputFile() instead of calling iobfileopen(stdin) a second time.

	* doc/Makefile.am: Fix pnm->png target.

	* src/lib/oogl/wa/Makefile.am: Fix dependencies.

	* doc/Makefile.am:
	Do not use convert, doesn't work on Cygwin (at least not for me). Use
	pnmtopng from the netpbm package.

	* configure.ac: Do not search for xforms dir in source/build directory.

	* configure: Do not keep it in CVS.

	* README.cvs: A list of tools needed to rebuild the documentation.

	* INSTALL.Geomview: Update xforms notice.

2006-07-22  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* configure.ac: Bump version to rc4.

2006-07-20  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/aclib/Makefile.am: Should use LTLIBOBJS, not LIBOBJS.

2006-07-19  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* Makefile.am: *** empty log message ***

	* Makefile.am: Blah

	* src/lib/oogl/util/iobuffer.c: Remove debugging statements.

	* src/lib/oogl/refcomm/streampool.c:
	Open named pipes RDWR to always leave one active writer,
	PoolSleepFor() is no longer necessary then.

2006-07-18  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/oogl/refcomm/streampool.c:
	Additional comments about why better opening a pipe in read-write
	mode; opening O_RDWR leaves at least one writer on the pipe:
	ourselves. This way select may work as usual ...

	* src/lib/oogl/refcomm/streampool.c:
	I'm still a little bit puzzled w.r.t. to named pipes and select and
	blocking/non-blocking IO.

	* src/lib/oogl/util/iobuffer.c:
	Correct handling of O_NONBLOCK if HAVE_FCNTL (for efficiency, if
	iobuffer.c is still broken, we have force HAVE_FCNTL to 0).

2006-07-16  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	Ported to new geomview stuff.

	Slight changes; named pipes must not be run in non-blocking mode, I think.

	those are defined but not used.

2006-07-05  Lloyd Wood  <L.Wood@surrey.ac.uk>

	* src/lib/mg/rib/mgribdraw.c: Checking in rendering transparency patch:
	http://sourceforge.net/tracker/index.php?func=detail&aid=1231146&group_id=9736&atid=309736
	provided by Chun-Chung Chen - cjj.

2006-06-26  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/oogl/util/seekpipe.c:
	seekpipe_read() was severly broken (end of function reached without
	return statement. Gnah.

	* src/lib/camera/camera.c, src/lib/geometry/cmodel/cmodel.c, src/lib/geomutil/crayplutil/crayBezier.c, src/lib/geomutil/crayplutil/crayInst.c, src/lib/geomutil/crayplutil/crayList.c, src/lib/geomutil/crayplutil/crayMesh.c, src/lib/geomutil/crayplutil/crayPolylist.c, src/lib/geomutil/crayplutil/crayQuad.c, src/lib/geomutil/crayplutil/crayola.c, src/lib/geomutil/crayplutil/crayolaP.h, src/lib/geomutil/dim/dim.c, src/lib/gprim/bbox/bboxclass.c, src/lib/gprim/bezier/bezdice.c, src/lib/gprim/discgrp/dgdirdom.c, src/lib/gprim/discgrp/dgenum.c, src/lib/gprim/discgrp/matlist.c, src/lib/gprim/discgrp/stack.c, src/lib/gprim/discgrp/weeks_dirdom.c, src/lib/gprim/geom/extend.c, src/lib/gprim/geom/geom.h, src/lib/gprim/mesh/meshpick.c, src/lib/gprim/sphere/sphereP.h, src/lib/gprim/sphere/spherecreate.c, src/lib/gprim/tlist/tlstream.c, src/lib/gprim/vect/vectdraw.c, src/lib/gprim/vect/vectpick.c, src/lib/mg/common/mgtexture.c, src/lib/oogl/lisp/lisp.c, src/lib/oogl/util/futil.c, src/lib/oogl/wa/Makefile.am, src/lib/oogl/wa/fsaparse.l, src/lib/pointlist/ptlBezier.c, src/lib/shade/appearance.c, src/lib/shade/appearance.h:
	va_args issues, sphere command works again.

	* configure.ac: Bump version to 1.8.2-rc1

2006-06-25  Lloyd Wood  <L.Wood@surrey.ac.uk>

	* configure: It's INSTALL.Geomview with a capital G.

	* INSTALL.Geomview, configure:
	Updating text of documentation referring to reconf to reflect recent
	changes by rotdrop. (It's still a good idea to direct users to the reconf
	script, rather than just autoreconf -i, in case the reconf script needs to
	do anything else in future.)

2006-06-24  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* doc/Makefile.am:
	Install png figures in info directory (although at least _MY_
	emacs/xemacs cannot handle them).

	* src/lib/oogl/wa/.cvsignore, doc/figs/.cvsignore:
	Ignore some more auto-generated files.

	* doc/Makefile.am: It is "dist-hook", not "distlocal".

	* .cvsignore: Add geomview dist directory (created during "make dist").

	* Makefile.am: Remove almost everything with "make maintainer-clean".

	* .cvsignore: Ignore INSTALL (auto-generated).

	* .cvsignore: Remove build/packbuild.

	* acconfig.h: use new autoheader interface.

	* INSTALL: Auto-generated.

	* configure: Resurrect dummy configure script.

	* NEWS: Update, add 1.8.2 release note (for future use).

	* Makefile.am: Remove traces of old build-system.

	* reconf: Just redirect to "autoreconf -i" as should be.

	* build.in, packbuild.in:
	People should use the normal "configure && make" stuff.

	* .cvsignore: Ignore the tar-balls generated by "make dist".

	* configure:
	Don't keep auto-generated files in CVS. Use 'autoreconf -i' instead.

	* configure.in: Renamed to configure.ac.

	* configure.ac: Renamed.

	* src/lib/oogl/wa/yystype.h:
	Define YYSTYPE_IS_DECLARD, otherwise recent flex/bison combo's define
	it to int, which is not what we want.

	* src/lib/oogl/wa/fsaparse.l, src/lib/oogl/wa/fsaparse.y:
	Include string.h (missing prototype issue).

	* src/lib/oogl/wa/Makefile.am:
	Include "BUILT_SOURCES", i.e. wa.lex.c etc into the distro. Remove stuff with "make maintainer-clean".

	* src/lib/oogl/wa/wa.lex.c, src/lib/oogl/wa/y.tab.h, src/lib/oogl/lisp/clisp.h, src/bin/example/.geomview-example, src/bin/animate/.geomview-animate:
	Not in CVS, because the maintainers can generate them.

	* src/bin/geomutil/bdy/Makefile.am, src/bin/geomview/Makefile.am, src/bin/geomview/x11/Makefile.am, src/lib/oogl/lisp/Makefile.am, src/bin/animate/Makefile.am, src/bin/example/Makefile.am:
	Make sure "make distclean" deletes everything which is not included in
	the distributions, because that is what distclean is for.

	* src/bin/geomutil/oogl2vrml/.cvsignore: Ignore oogl2vrml2

	* src/bin/geomutil/bdy/.geomview-drawbdy: Generated during "make".

	* m4/geom_local.m4, m4/lf_local.m4: Fix "underquoted" AC_DEFUN's

	* doc/.cvsignore, doc/Makefile.am, doc/README, doc/geomview.texi:
	Move to a recent TeXinfo release, this simplifies things a lot, even
	support for HTML is now built into makeinfo.

	* doc/figs/.cvsignore: Ignore .png, .eps, .pdf

	* doc/figs/eps2pdf1.sh: Use epstopdf, if available.

	* doc/figs/trefdodecinter.pdf, doc/figs/tools.pdf, doc/figs/initial.pdf, doc/figs/light.pdf, doc/figs/load.pdf, doc/figs/main.pdf, doc/figs/mat.pdf, doc/figs/myfilelist.pdf, doc/figs/save.pdf, doc/figs/secondlinelist.pdf, doc/figs/cam.pdf, doc/figs/color.pdf, doc/figs/command.pdf, doc/figs/fig2.pdf, doc/figs/ap.pdf:
	Only keep the original PS files, everything else can be generated.

	* doc/figs/color.ps, doc/figs/command.ps, doc/figs/initial.ps, doc/figs/light.ps, doc/figs/load.ps, doc/figs/main.ps:
	Those files were in Landscape mode, unluckily. Back-converted to portrait,
	kept care to do this pixel-wise, so the pictures should be unchanged.

2006-06-23  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* configure.in: Explicitly link with -lXpm, at least I need it.

2006-06-23  Lloyd Wood  <L.Wood@surrey.ac.uk>

	* INSTALL.Geomview: Adding explanatory note about reconf use.

	* reconf: Indicate revision of reconf script.

	* configure: Adding some hints concerning autoreconf and automake.

	* reconf:
	autoconf presumes that any existing configure file is a good configure file.
	So moving any existing file to configure-old first to allow a new one to be
	created.

	* configure:
	Adding placeholder configure file as hint to new CVS users to run reconf to
	autoconf/automake configure and Makefiles.

2005-10-31  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/gprim/geom/create.c, src/lib/gprim/geom/geomclass.h:
	Some more va_list stuff; actually, my previous patch was incomplete
	(submitted over 18 months ago ...). Here comes the fix; the cvs
	version should work again with with patch, even on x86 and not only on
	x86_64 ...

	See

	http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14557

	The problem is that va_list is not only opaque, but ReallyOpaque
	(maybe (tm)??). va_list may even be an array_type. Then in the context
	of

	foo(va_list foo)
	{}

	already is not of type "va_list" _BUT_ of type "&va_list[0]". So:

	foo(va_list foo)
	{
		bar(&foo);
	}

	passes _NOT_ the base address of va_list to "bar()" _BUT_ the address
	of the piece of storage which holds the parameter "foo" which is _NOT_
	what we want (think about it!! This is JAIOCABD
	(JustAnotherInstanceOfCArrayBrainDamegedness) Oops.

	I did all this to make Geomview work on AMD64 with Linux. Actually, I
	DO NOT like the libc implementation of va_list, but we have to cope
	with it. Also, the changes _should_ not break archs/compilers where
	va_list is a structure and not of array-type.

	Hope this will be portable (_should_ be, but FIXME if not).

	* Makefile.am:
	Don't try to include stuff into the distro which is not there, the
	smr_SOMETHING macros are still missing in m4/

2005-02-21  Mark Phillips  <mbp@geomtech.com>

	* reconf:
	remove system-specific '--with-motif' option when ./configure is run

2004-05-02  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* src/lib/oogl/util/seekpipe.c:
	My previous commit did not even compile, I _very_ deeply apologize.

	* src/lib/oogl/util/futil.c:
	Binary formats where severely broken w.r.t. little-endian 64-bit
	archs. Keep the following in mind: _NEVER_ use "long" if you mean
	"32-bit wide". Either use bit-types defined by the OS (libc
	header-files), or assume that int's are 32-bits (maybe wrong) and that
	you do not have any knowledge about the size of long's.

	* src/lib/oogl/util/seekpipe.c:
	Add debugging code. To actually switch on debugging, the environment
	variable SEEKPIPE_DEBUG has to be set (to whatever value). The name of
	the output-file is controlled via SEEKPIPE_DEBUGFILE. The default is
	/tmp/seekpipe-foo.

	If set the data-stream will be copied to SEEKPIPE_DEBUGFILE.

	* src/bin/geomview/common/comm.c:
	On the client: Close the pipe-fd's after duping them to stdin and
	stdout, they are no longer needed.

2004-04-27  Claus-Justus Heine  <Claus.Heine@Mathematik.Uni-Freiburg.DE>

	* configure.in:
	Set CFLAGS to -O0 when checking for math-lib, some compilers already
	inline math-functions when used with -O2.

	* ChangeLog: Update.

	* src/bin/geomutil/oogl2vrml/Makefile.am, src/bin/geomutil/oogl2vrml/oogl2vrml2.c:
	Use oogl2vrml to create an oogl->VRML 2.0 converter. Most modern
	viewers do not understand VRML 1.0.

	* configure.in:
	Remove ALISTADDR and add check for /bin/csh versus /bin/sh.

	* acconfig.h:
	Remove ALISTADDR (was a BUG!). See notes for the big bunch of the
	other changed files.

	* src/lib/oogl/wa/wa.yacc.c: Auto-generated.

	* src/lib/oogl/util/glob.c:
	Resort to /bin/sh if /bin/csh is not found. At least _I_ don't have
	csh installed (don't like it, but that's OT). Default is to use
	/bin/csh as before.

	* src/lib/oogl/util/futil.c:
	fmemopen() is a GNU-stuff (AFAIK). So define _GNU_SOURCE to get the
	proper proto-type (makes a _MAJOR_ difference on 64-bit
	systems!!!!!!!!!!)

2004-02-22  Steve M. Robbins  <steve@nyongwa.montreal.qc.ca>

	* m4/lf_local.m4, Makefile.am, configure.in, ChangeLog:
	*** empty log message ***

	* ChangeLog: entries for previous configure and Makefile change.

	* Makefile.am, configure.in, m4/Makefile.am: 	* m4/Makefile.am: Remove.
		* Makefile.am (m4_files): Distribute the m4/*.m4 files.

		* configure.in: Take care to avoid using MS Windows "find"
		command.  Do not create m4/Makefile.

2004-02-21  Steve M. Robbins  <steve@nyongwa.montreal.qc.ca>

	* configure.in: Run autoupdate from autoconf 1.8.

	* m4/lf_local.m4 (LF_LINK_HEADERS): Generate the include symlink
	farm in $(top_builddir), as $(top_srcdir) may not be writable.
	Use "mkdir" to make the common include directory.  Newer autoconf
	no longer provides shell script mkinstalldirs.

	* Makefile.am (EXTRA_DIST): Do not list mkinstalldirs.

	* m4/Makefile.am: Remove.
	* Makefile.am (m4_files): Distribute the m4/*.m4 files.

	* configure.in: Take care to avoid using MS Windows "find"

2002-10-26  Steve M. Robbins  <steve@nyongwa.montreal.qc.ca>

	* configure.in: Bump version to 1.8.2.

2002-04-13  Steve M. Robbins  <steve@nyongwa.montreal.qc.ca>

	* Makefile.am (ACLOCAL_AMFLAGS): Set to "-I m4" so that the
	proper option is passed when aclocal is run.

2002-04-06  Steve M. Robbins  <steve@nyongwa.montreal.qc.ca>

	* INSTALL.Geomview: Document --with-xforms as the 
	configure flag.

2001-03-24  Steve M. Robbins  <steve@nyongwa.montreal.qc.ca>

	* configure.in: Do not add -XSVR4 and -common to CFLAGS when
	configuring with IRIX cc.

2001-03-21  Steve M. Robbins  <steve@nyongwa.montreal.qc.ca>

	* doc/Makefile.am (EXTRA_DIST): Remove motion.pdf.

	* configure.in: Set revision to 1.8.1.

	* m4/geom_local.m4 (GEOM_FIND_I_OPTION): Respect prior setting of
	$CPPFLAGS while probing.

2001-03-19  Mark Phillips  <mbp@geomtech.com>

	* doc/motion.tex: new file added to release; documents the
	  mathematics behind Geomview's motion model.  For use by
	  developers (not needed by regular users).

2001-02-21  Steve M. Robbins  <steve@nyongwa.montreal.qc.ca>

	* configure.in: Add AC_FUNC_SETPGRP.

2001-02-18  Steve M. Robbins  <steve@nyongwa.montreal.qc.ca>

	* configure.in: Add option --with-build-path.  Use AC_PATH_XTRA.
	Correct the X library link order.  Make sure to check
	/usr/local/lib for all libraries that check /usr/local/include.
	Check for <forms.h> in $x_includes and $x_includes/X11.  Make sure
	both the includes and the libs are correct before using FORMS.
	Announce whether Xmu is found.  General tidying up.

2001-02-17  Steve Robbins  <steve@nyongwa.montreal.qc.ca>

	* acconfig.h: Close comment above define for HAVE_FMEMOPEN.

	* configure.in: Check endianness and check for header netinet/in.h.

	* doc/Makefile.am: Only build "geomview.pdf" on target "pdf".

2001-02-11  Steve Robbins  <steve@nyongwa.montreal.qc.ca>

	* m4/geom_local.m4 (GEOM_CHECK_XFORMS): New.  If XFORMS library is
	available, set variables for finding includes and libraries, emit
	warning if XFORMS is not available.


2001-01-16  Steve Robbins  <steve@nyongwa.montreal.qc.ca>

	* configure.in: removed redundant --with-forms argument; its
	effects got overwritten by --with-xforms, anyway.

2000-11-23  Steve Robbins  <steve@nyongwa.montreal.qc.ca>

	* src/Makefile.am (geomview): look for "gvx" in $(moduledir)
	rather than $(bindir).
	(CLEANFILES): clean geomview script.

2000-11-20  Mark Phillips  <mbp@geomtech.com>

        * release 1.8.0  (see NEWS file for summary)

2000-11-19  Mark Phillips  <mbp@geomtech.com>

	* texi2pdf doesn't seem to include figures; for now revert
	  to dvipdf to generate pdf version of manual

2000-11-17  Mark Phillips  <mbp@geomtech.com>

	* doc/Makefile.am: refer to $(srcdir)/geomview.texi
	  rather than geomview.texi when invoking tex

2000-11-15  Mark Phillips  <mbp@geomtech.com>

        * removed 'stamp-h.in' and 'aclocal.m4' from CVS, since they
          are derived files.

        * cleaned up & documented 'reconf' script, used to bootstrap
          a fresh Geomview tree checked out from CVS.

        * INSTALL.Geomview: re-wrote XFORMS configuration instructions to
          reflect the fact that XFORMS (Linux Intel version) is no longer
          part of the Geomview distribution; users who want it now
          download it separately and unpack it into the top-level Geomview
          directory before configuring Geomview.

        * src/lib/Makefile.am: explicitly mention 'forms' dir in SUBDIRS
          now, rather than having it be conditional based on whether
          xforms is present, since this dir only contains a .h file which
          can be installed even if xforms isn't present.

        * configure.in: Changed all variables that mention forms to say
          'xforms' instead, for consistency.  Added caching of many
          variables so their values can be shared with other configure
          scripts.  Changed OOGLLIBS to use top_geom_builddir instead of
          top_builddir, so that its value can be used in other configure
          scripts.  Added check to detect subdirs of src/bin having
          additional configure.in's, and to call AC_CONFIG_SUBDIRS with
          them.

        * m4/geom_local.m4: added macros GEOM_LOG_MSG,
	  GEOM_GET_CACHED_VALUE, and GEOM_REQUIRE_XFORMS.  Removed
	  verbosity from GEOM_FIND_I_OPTION and GEOM_FIND_L_OPTION operate
	  quietly so that whoever would call them can print messages even
	  if the corresponding values are coming from the cache (rather
	  than actually calling GEOM_FIND_I_OPTION/GEOM_FIND_L_OPTION).

        * Makefile.am: removed xforms from SUBDIRS

        * removed xforms directory from distribution; re-wrote
          configure.in & friends to just notice whether xforms is present
          and use it if so, or quietly (with a warning) ignore it if not.

2000-11-09  Mark Phillips  <mbp@geomtech.com>

        * configure.in: improvements to the test for -lgl so that it
          gives a false negative less often; added message to output
          saying what geomview version is being configured, to aid in
          deciphering other people's 'configure' output

        * src/bin/geomutil/vrml2oogl/Makefile.am: added -lm to vrml2oogl
          link line where necessary

        * src/lib/oogl/util/futil.c: corrected USE_FSTROPEN_1 definition
          for AIX/__osf__/__hpux/__FreeBSD__ case

2000-11-05  Steve Robbins  <steve@nyongwa.montreal.qc.ca>

        * Makefile.am (distclean-local): Remove "include" directory.

        * doc/html/Makefile.am (EXTRA_DIST): 
        * doc/Makefile.am (EXTRA_DIST): List files explicitly, to avoid
          distributing CVS directory.

        * configure.in: Check for either "texi2pdf" or "dvipdf".

        * doc/Makefile.am (.texi.pdf): Build PDF files using "texi2pdf"
          (from GNU Texinfo package), if available.

        * data/Makefile.am (geomdata_DATA): List data files to install.

        * configure.in: Set geomdatadir variable, allowing easy overriding
          at configure time.

        * src/Makefile.am (geomview): 
        * Makefile.am (geomview): 
        * geomview.sh (GEOMVIEW_LOAD_PATH): Do not assume data lives in a
          subdirectory of $GEOMROOT.

2000-11-04  Steve Robbins  <steve@nyongwa.montreal.qc.ca>

        * src/Makefile.am (geomview): 
        * Makefile.am (geomview): 
        * geomview.sh (GEOMVIEW_EMODULE_PATH): Do not assume that modules
          live in a subdirectory of $GEOMROOT.

        * configure.in: Change "modulesdir" to "moduledir", so that
          "module_PROGRAMS"

2000-11-02  Steve Robbins  <steve@nyongwa.montreal.qc.ca>

        * doc/html/Makefile.am (geomview_toc.html): Use $srcdir to refer
          to a file in the sources.

        * Makefile.am (geomview): 
        * src/Makefile.am (geomview): Refer to `geomview.sh' using
          $top_srcdir.

        * configure.in: The macro AC_OUTPUT will only create a single
        directory level at a time, so we must list the files in directory
        `a/b' before those in directory `a/b/c'.

2000-11-01  Mark Phillips  <mbp@geomtech.com>

        * release 1.7.10 (see NEWS file for summary)
        
        * src/lib/oogl/util/futil.c: Added tests to 'configure' to decide
	  whether to use fmemopen() instead of CC_fmemopen__FPci() on
	  linux systems in the implementation of fstropen.  Also added
	  "--enable-fstropen-1" flag to 'configure' to allow forced use of
	  manual implementation of fstropen.  These changes are in
	  response to reports of Geomview crashing upon startup, while
	  reading the default appearance (via a call to fstropen), on some
	  newer Linux systems.
            [thanks to Mikhail Tchernychev <mikhail_tchernychev@yahoo.com>
             and Belinda Marchand <marchand@ecn.purdue.edu>]

        * src/lib/oogl/wa/fsaparse.l: removed duplicate rules for "min"
	  and "bfs"
            [sent by Steve Robbins  <steve@nyongwa.montreal.qc.ca>]

        * src/bin/geomview/common/comm.c: added preprocessor condition to
	  allow compilation on the Alpha
            [sent by Tamara Munzner <tmm@pa.dec.com>]

2000-10-29  Steve Robbins  <steve@nyongwa.montreal.qc.ca>

        * configure.in: also try $x_includes when searching for Xm/Xm.h

2000-10-20

	* release 1.7.9 (see NEWS file for summary)

2000-10-14

	* release 1.7.8 (see NEWS file for summary)
        
1.7.7   August 22, 2000
   Added some of the external modules to the distribution, but haven't
   actually tested them.

   Updated the documentation to reflect the fact that the geomview-users
   mailing list is now hosted at lists.sourceforge.net.

1.7.6   May 25, 2000
   Converted source tree (geomview only; no external modules yet)
   to use GNU autoconf
   
   gv_rawevent now actually is passed an 'unsigned long' (which
   is what it expected all along, but previous was passed an
   'int') for the time value.  This had been causing mouse
   motions to fail on 64bit RS6000 running AIX 4.3.2.
        
   Many function prototypes fixed, and other warnings turned up
   by 'gcc -Wall' fixed.  (Most of them had to do with functions
   that were implictly declared to return an int not returning
   a value).
        
   Changed Geomview's X application name from "gv" to "geomview",
   to avoid possible conflicts with other applications named "gv,
   such as ghostview.  This affects the name used for X resources
   that apply to Geomview.  If you want to force Geomview to use
   the old "gv" name for backward compatability, set the environment
   variable GEOMVIEW_X_NAME=gv in the "geomview" shell script (be
   sure to 'export' this variable too).

1.7 February 13, 2000
   This version of the software is the same as 1.6.1p9d; the only
   difference is in the documentation, which has been substantially
   changed to reflect the fact that the Geometry Center is now closed
   and that the new home for Geomview is http://www.geomview.org.

1.6.1p9d  August 18, 1998

   Fixed coloring of N-D OFF objects noted by James Lawrence.

   Fixes to many obscure bugs and great wads of lint, suggested by
   David Kaelbling of SGI.

1.6.1p8  March 13, 1998

   Fixes to compile with GNU glibc, and on Linux under non-x86 machines.

   Geomview panels: don't limit FOV < 180 if in orthographic mode.

   Fix more bugs in anytooff: convert VECTs even if appearance suppresses
        faces and edges; preserve edgecolor property in vects.

   Fix togeomview "Bad address" error: execvp() with no trailing NULL!

1.6.1p7  November 20, 1997

   Geomview:
     Fix egregious vertex-picking bug, present in all earlier 1.6.1 versions,
     where the returned vertex index was wrong (it returned one of the
     adjacent vertices instead).

     Include lighting properly in saved .rib files.

     Use OpenGL texture_object extension if available; this improves
        multiple-texture performance dramatically on some systems.

     Automated making multiple gvx binary versions (MESA, native, etc.).

   Distribute MapleV4 version of gvplot as well as earlier ones.
   Thanks to Loris Renggli, loris@math.fsu.edu, for supplying a patch.
   Repaired  geomview/x11/geomview-x11 script so its Makefile can
   customize it properly again (broken in 1.6.1p6).

   Fix togeomview, which sometimes could fail spuriously with "Bad address".

1.6.1p6  August 29, 1997

   Geomview:
        Now seems to work, more or less, with lesstif.
        Avoid crashing in X11 renderer: work around DEC Alpha cc and gcc bugs.
        Don't draw into iconified windows, even if told to redraw via GCL.
        Postscript-save mode produces postscript which doesn't fail
            when invoked with non-empty Postscript stack.
        New "ppmmesa" snapshot type.  If compiled with MESA OpenGL-like
            library, allow arbitrary-res off-screen rendering using
            (snapshot CAMID FILENAME ppmmesa ...)
         Presence of this indicated by "(MESA)" in (geomview-version) string.
        Allow control over texture-mapping quality (interpolated or not).
        Try to produce usable display colors (not all black) on 8-bit Indigos.
         I'm told this still doesn't work, though.
           
        geomview script accepts "-opengl", "-mesa", "-x11" etc. flags,
            and selects alternate gvx.{OGL,MESA,X11} binaries if installed.

   anytooff handles "dice" appearance tag for Bezier & Sphere objects,
        and gets the right color for colored VECTs.

   emodule_wish.sh script sets tcl/tk envariables, making it easier
     for emodules to use "wish".

   Make math2oogl really, really turn off non-blocking mode on its named pipe.

   vrml2oogl now invokes gzip to read compressed files,
        passes color into OOGL edgecolor as well as surface color, and
        handles text by invoking "hvectext".

   OOGL library changes:
     prototypes at last for geometry functions.
     new cleaner way to organize mg lights; they're now shared and refcounted.
     
   
1.6.1    December 10, 1996

   Source distribution no longer uses GL-based FORMS library.
   Geomview's X/Motif interface is now the primary version,
   which the manual now describes.  Many modules rewritten
   by Nils McCarthy, Tim Rowley, and others using Tcl/Tk.  Many FORMS-based
   external modules adapted to use XForms (object libraries available from
   ftp://laue.phys.uwm.edu/pub/Xforms; see INSTALL).

   This release finally supports the extensions needed for Tamara Munzner's
   weboogl package.

  Known problems:

   Many changes aren't mentioned in this CHANGES file (though I think the
   significant ones are).

  Porting:

   Should now work under FreeBSD, and HP-UX 10.x.
   Has been tried in some new environments, including Sun UltraSparc with
   Creator3D card under Open GL, and Mesa Open-GL-like clone under Linux and
   HP-UX.  Various portability problems fixed in the source code.

  Modules:

   Some modules from earlier releases are omitted here:

     PS Snapshot's functionality is superceded by Geomview's PS Save mode.
     4dview is superceded by NDview, and in any case it depends on some
        GL-based FORMS code which hasn't been ported.
     Crayola, Warp, and parts of NDview depend on old FORMS code.

   Some new modules are added:

     Crayola, NDview, NDdemo, and Labeler are now in Tcl/Tk.
        You'll need to install Tcl/Tk in order to compile them; see INSTALL.

     Also in Tcl/Tk are some new N-dimensional utilities by Brian Luense:
        3D-Snapshot (save a projected copy of the current N-D object),
        Colormap (interactive N-D colormap controls), and
        Slicer (N-dimensional clipping).

    FORMS modules were only minimally ported to X-Forms.  You can't use
        the new Forms designer to change their interfaces, since the new
        designer writes .c files in an incompatible (though superior) way.
        The FORMS section in the Geomview manual needs to be updated.

  Applications:

    New "vrml2oogl" and "oogl2vrml" converters, written by Daeron Meyer
    and Tamara Munzner respectively.  "vrml2oogl" uses the C++ QvLib library,
    included here; if you use GNU g++ to compile it, it seems to require 2.7.2.

    "anytooff" now more efficient on large data sets, and preserves
    appearance information where possible.

    Maple graphics now pay attention to color, and can now be displayed on
    remote computers; see doc/gvplot.doc.

    New command-line text generator "hvectext" uses Hershey stroke fonts.

    Benchmarks for various platforms, with a Makefile to run your own,
        are in data/speedtests.


  Geomview graphics:

   Supports Open GL as well as GL and X renderers.  Future development will
   most likely focus on Open GL.

   Texture mapping available in GL and Open GL (but not plain X11) renderers.
   Texture coordinate must be explicitly specified.  Images may be sgi,
   ppm/pgm/pbm, or tiff or gif if netpbm toolkit installed.
   See data/geom/textured/* for some examples.

   New built-in PostScript renderer by Tim Rowley replaces PS Snapshot
   module -- respects appearances, but still uses only painter's algorithm
   for hidden-surface removal.

   New in-memory renderer (related to X renderer) writes arbitrary-size
   PPM images of geomview scenes.

   Single/double-buffered switching works in Motif version too.

   You can specify an image as a window background.

   X11 renderer on 8-bit colormapped displays defaults to 5x5x5 color cube,
   to leave more color-table slots available.  New GEOMVIEW_COLORLEVELS
   environment variable may be set to "6" to get the old 6x6x6 behavior.

   Some binary distributions include two geomview binaries, both
   bin/*/gvx with X11 renderer, and bin/*/gvx.OGL, with Mesa OpenGL-clone
   libraries.  "geomview -opengl" invokes the Open GL version.

  OOGL data formats:

   More-robust geometry parser never backtracks on valid input,
   and should now reliably read data from pipes (rather than almost-reliably
   as before).  "Lincoln" objects no longer supported.

   New "origin" and "location" fields in INSTs allow fixing objects in
   screen or camera or etc. coordinates, e.g. to paste text or UI elements
   onto objects or onto the screen.  (No built-in geomview text yet, though.)

   "input-translator" command allows specifying an external program to
   translate a file beginning with a particular string into OOGL format.
   This hack lets us read ASCII VRML files directly using vrml2oogl.

   New appearance attributes for texture-mapping, concave polygons,
   shaded lines, back-face culling, Bezier patch dicing.

  Geomview command language:

   (snapshot ...) commands -- except SGI format -- allow piping PPM or
   PostScript data to a shell command as well as writing to a file.
   PPM images may be arbitrary size.

   (background-image ...) puts an image up as a window background.

   (pick-invisible ...) lets picking depend on appearance
   (though the default is still to ignore appearances).

  Geomview UI:

   Keyboard shortcuts work in Motif panels!
   Single ESC no longer exits from geomview; use ESC ESC.
   Motif panels are now resizable.

   GL/FORMS user interface is no longer available in this release.

   Now terminates cleanly, notifying any running modules,
   if sent interrupt/hangup/terminate signals.

  Geomview documentation:

    Manual now included in HTML form (see doc/geomview_toc.html)
    as well as Texinfo and (in binary packages) Postscript.

    Manual updated to describe the Motif user interface.
    It also includes a Tcl/Tk sample module, though without commentary.
    The commentary for modules using the FORMS library is no longer accurate,
    though probably still somewhat useful.



1.5     October 21, 1994

   Source distribution now includes support for generic X/Motif
        (Sun, HP-UX, Linux, probably other systems) as well as SGI
        and NeXT graphics.

   Geomview motions:

     INCOMPATIBLE bug fix in the GCL command language:
        Motions defined with respect to the object itself, e.g.
         (transform world world world translate 0 0 1)
        had been interpreted with the wrong sign.  This is now fixed.
        Application programs which depended on this bug (including gvclock
        and stereo) need to change accordingly.

     Documentation fix: GCL rotations (transform/transform-incr/transform-set)
        are given in radians, not degrees.

     New motion-animation commands:
        The (transform ...) command now allows a simple form of animation.
        If given an amount of time, it arranges to move by exactly that amount
        during approximately that many seconds, either at constant speed
        or with smooth start and stop.

     Scaling now happens with respect to the selected "center" object,
        not the object's own origin.  There's a new (transform ... scale ...)
        subcommand.

   Keyboard input:
     New (event-keys) and (event-pick) commands can suppress geomview
        interpreting keyboard input as commands and rightmouse-clicks as
        picking, in graphics windows.  Useful for modules which want to impose
        their own interpretations on events.

   Non-Euclidean spaces:
     Newly created cameras now correctly live in the current (possibly
        non-Euclidean) space.   They had been always Euclidean,
        despite misleading window titles.
        
   N-D projection:
     New "nOFF" object is a collection of 0-, 1- or 2-dimensional polygons
        in N-dimensional space.
     N-D coloring projection axes can be with respect to any coordinate system.

   Two-sided surface coloring:
     The "backdiffuse" material field, if defined, is interpreted as the
        reverse-side's diffuse color.  Works whenever software shading
        is enabled (i.e. always on generic-X systems); also works on those
        SGI systems whose hardware supports two-sided GL lighting.  There's
        no control panel for this feature yet but GCL commands can, e.g.
        (merge-ap world { material { backdiffuse .7 .5 0 } })


   There were a number of portability improvements in the X version,
        fixing bugs for Sun/Solaris, HP-UX, Linux, DEC OSF, AIX.

   Code is now more careful to avoid floating-point exceptions, which
        cause trouble on some machines.

   Yacc and lex, which were needed for one library, are no longer essential.



   Substantial improvements to the 3D graphics in the X11 version of Geomview:
        - Uses X Shared Memory extension (when available) for
                quick rendering of polygons and lines to X11 framebuffer
        - Support for 1, 8, or 24 bit deep X displays added
        - Optional dithering for 8 bit displays
        - Dithers 1 bit displays
        - Optional zbuffering (for hidden line/surface removal) added
        - Smooth shading added
        - Support for line thickness > 1 added
        - Clipping planes added

   Numerous fixes/additions to the X11 Geomview Motif interface:
        - Window positioning commands work (under most window managers)
                except for the Load and Save panels
        - fixed edit menu
        - added ability to type in RGB values in color panel
        - added numeric displays for sliders on material panel
        - added option menu on camera panel for choosing
                hidden surface removal method
        - added toggle button on camera panel for activating/deactivating
                dithering of colors (only shows up in 8 bit mode)

   Unlike the beta-release X graphics, the new version transmits complete
        images, not polygons, to the X server.  It's faster for local
        displays; can be slow when the display-to-geomview connection
        traverses a slow network link.

   New associated packages:

    gvplot/writeoogl, a Maple package for displaying Maple 3-D graphics
        objects in Geomview or saving them as OOGL files.  See doc/gvplot.doc.

    clip, a new command-line program based on Ginsu.  Allows clipping
        OOGL objects against spheres and cylinders as well as planes.


1.4.3   July 24, 1994

   Most changes since 1.4.2 were to fix minor bugs & improve portability.

Documentation
   Documented the OOGL "COMMENT" object.  Clarified explanation of transparency.

Geomview
   New ui-freeze command (effective on SGI only) allows suspending/resuming
     updates to UI panels, for decent performance when lots of things are
     changing.

   Portability mods: ensure FNDELAY is defined; pass the proper
     argument type to wait3/waitpid (union wait vs int).

   Fix ``normalization'' command; it had failed on "all" and "keep".

   Fix ``ND-xform-get'' command; it had returned the inverse of the
     correct matrix.

   Make ``set-conformal-refine'' command process its arguments properly.

   Call proper version of setpgrp() when spawning external modules;
     ensures we can properly kill them when exiting.
   Work around lost SIGCHLD signals when we kill an e-module invoked with
     ``(emodule-run exec program ...)''; this caused geomview to hang when
     trying to quit while such a module was running.
   Erase comm link (named pipe/socket) if it already exists but is of the
     wrong type (-M option).  ["togeomview" and "math2oogl" fixed similarly.]


OOGL libraries
   COMMENT objects can't be picked.  (Due to bugs fixed here, scenes with
        COMMENTs could sometimes yield totally spurious pick results.)

   Compute bounding spheres of 3-D objects properly, even when not normalized
     to w=1.  Affects geomview's Look command.

   Draw N-D SKEL objects even when not in N-D mode.
   Maintain mg drawing flags correctly, so driver applies proper colors, etc.,
     when drawing SKEL and VECT objects.

   Draw SPHERE objects with degenerate corner at x=1, so the Bezier normals
     come out right.

   Allow binding an appearance to a reference to a handle, e.g.
     { appearance { +edge } : fred }, by inserting an INST to hold the handle.

   Concentrate all stdio dependencies in src/lib/oogl/util/futil.c.
     Handle Linux 1.0.

   Implement acosh() correctly!

X graphics
    Allow drawing into subregions of the graphics window; needed for stereo.


External modules

 PSSnap
   Make isolated points visible.
   Ensure lightness values don't exceed 1.0.

 mgexample
   Handle lighting properly.  Allow giving data file on command line.

Configuration
   New "make clobber" rule cleans and removes targets (except libraries).
    Handy for saving space after building & installing the source distribution.

   "all" is now the sole first target in Makerules.src, to avoid confusing
        RS/6000 make.

   Expect Motif include files in /usr/include/X11/Xm/... on HP-UX.
   Define default settings for CPLUSPLUS (compiler name) for SGI and RS/6000.

   Compile on RS/6000 with "-ma" flag to allow unrestricted use of alloca().

   SunOS 4.x: set "BSD" flag, initially for choosing version of setpgrp().

   Finish incorporating SYSLIBS, etc. macros into makefiles.

   Omit -lXt when linking with mgexample, to avoid spurious link errors on Sun.



1.4.2  April 20, 1994

Beta X11 source distribution supports HP PA-RISC, DEC Alpha, RS/6000,
    Solaris, and Linux (0.99), in addition to SunOS 4.x.

New external modules:
    SGI version:
        Maniview          (3-manifold viewer),
        NDview and NDdemo (N-dimensional viewer and demonstration program)

    X11 version now includes Animate and PS Snapshot modules.

Configuration

   Make SYSLIBS, SYSXLIBS, etc. settings -- set in makefiles/mk.* files --
       be used when compiling all programs.  Ditto for ALLOOGLLIBS,
       so new OOGL libraries can be added in one place.

Geomview

   Picking now works in X11 Geomview.

   Maintain reference counts better, avoiding memory leaks.
   Fix various cases that caused core dumps:
        - (interest ...) command entered in the Command panel
        - sending message to an external module started with -start option.
        - (echo (ND-xform ...))

   Make RIB snapshotting work in conformal and N-D viewing modes.
   (dimension) command now returns the correct setting, and
        (dimension N) does nothing if we're already in that dimension.
   Correctly choose a new current camera when the "focus" camera is deleted.
   Don't crash when sending messages to an external module started with -start
        command-line option.

   Make a crude estimate of bounding-box size for N-D objects, so "Look At"
       can begin to work.  It's only roughly right, and that only for objects
       roughly centered on the origin.
   Automatically switch all cameras into N-D mode when (dimension) is set,
        if (ND-axes) have not yet been specified.
   New (ND-xform-get) command returns N-D transform between two objects.
   More documentation on ND-axes, ND-xform, ND-color commands.

SGI Geomview (actually FORMS library)
   Add X copy/paste facility to FORMS text input fields.

NeXT Geomview
   Deactivate color panel while changing its color -- don't be fooled into
       thinking the user selected a new color.

PS Snapshot
   Make isolated points visible.
   Draw uncolored points and lines in black; default had been nearly white,
        almost invisible.

Mathematica -> OOGL converter
   Add an XDisplay option, allowing mathematica to run on one machine,
        geomview on another, and send geomview's X display to a third machine.
   Handle escaped newlines in Mathematica's output, preventing strange
        parsing errors.

OOGL libraries
   New N-dimensional OOGL object types: nSKEL and nMESH.
   pick.h now correctly describes interpretation of pick arguments, and
        gives brief usage example.
   Waste less memory when loading Quads.  malloc(big)/realloc(small) can lose!
   GL graphics: leave mixed-model GL/X windows alone.
   Next graphics: allow setting window depth; allow lights to live in other
        coordinate systems.
   New "keepcolor" appearance keyword tags objects as being immune to N-D
        recoloring.
   OOGL objects containing an appearance attached to a handle/file reference
        now work correctly, rather than modifying the handle;
        the reference is silently wrapped in an INST.
   Various minor bug & portability fixes.


1.4.1  November 9, 1993

Distribution includes both NeXT and SGI versions.

    New modules included:
        crayola  (SGI and NeXT) coloring program
        warp     (SGI and NeXT) interactive object warping
        ndviewer (SGI only)     N-dimensional viewer (currently only 4D objects)
        cplxview (SGI only)     graphs of complex functions
        clipboard (SGI only)    cut, copy and paste objects
        drawbdy    (SGI and NeXT) find and draw the boundary of an object
        flythrough (SGI only)   Not Knot hyperbolic 
        gvclock   (SGI and NeXT) 3D clock, demonstrates real-time motion
        maniview  (SGI only)    3-manifold viewer
        trigrp    (SGI only)    explore triangle symmetry groups
    plus source for all the existing modules.


Documentation:
    New manual!  doc/geomview.tex (TeX version) and doc/geomview-*
        (GNU texinfo version) explain Geomview in far more detail than
        previous documentation.  They strictly describe Geomview on the Iris,
        but much also applies to the Next.
                
Configuration:
    SITE makefile variable selects one of several site-specific
        configuration settings, namely installation directories for binaries
        (BINDIR), manual pages (MANDIR), and Mathematica scripts
        (MMAPACKAGEDIR).  Settings stored in
        makefiles/mk.site.{default,private,public}.  ``make instprivate''
        and ``make instpublic'' are ``make install'' variants that use the
        latter two.

    Prevent 'make' from failing if C++ compiler isn't present; just don't
    compile the C++ programs.


Geomview, General:

    Extend implementation of conformal transformations.
        Conformal mode, which had been allowed only in hyperbolic space,
        is now also meaningful in Euclidean space, where it amounts to
        inversion in the unit sphere, and spherical space, where it's
        a stereographic projection from the 3-sphere into Euclidean 3-space.
        New command (set-conformal-refine).

    Read both ~/.geomview and ./.geomview, in that order.

    New -noinit command-line option suppress reading all .geomview files.

    Implement Olaf Holt's design for N-D viewing by projection.
        New commands (ND-axes) (ND-xform) (ND-color).
        (Invoked by ndviewer and cplxview modules.)

    Keep track correctly of which window the mouse is in.
        Had sometimes gotten confused if a window was uncovered.

    Allow disabling "override" status.  New Override button & (ap-override)
        command selects whether appearance controls should suppress
        objects' own settings, or just provide default values.

    New (camera-prop) command allows setting the object used to show cameras
        when "Draw Other Cameras" selected (e.g. see file "camera-frustum").

    Mention Next variants to mouse usage (alt + left = middle, etc.)
        in Help message.

SGI Interface:
    Add transparency controls to materials panel.
        (No transparency supported on NeXT.)

    Color picker has numeric RGB input.

    Buttons for motion controls (Obscure) and Override control (Appearance).

    Add focal length and software shading controls to camera panel.
        "vl" keyboard shortcut sets camera focal length.

    Limit picked projected Z values to -1 .. +1, so we can only pick things
        that lie between the clipping planes!


Motions:
    Really stop motions of objects when we reset them.

    Controllable inertia, constrained motion, own-coordinate-frame motion
        ('ui', 'uc', 'uo' key sequences).

    Make more use of the ``focal plane''.  Look At button sets focal distance.
        Shift-rightmouse-click selects a focal point; also becomes center of
        rotation.  Translations are interpreted as at the focal plane,
        so objects at the focal distance should move with the mouse.

    Use ordinary, no longer scaled, translations.
        Let the scaling be based on the frame camera's focal length,
        set e.g. by Look or etc. operations.

    Pay attention to window aspect ratio and camera focal length when moving.

    Add more parameters to (look-encompass-size ...) indicating desired margins
        for setting near and far clipping planes.


Geomview, Graphics:
    Pay proper attention to override bits in Next and RenderMan drawing
        libraries; ensures that objects will be the color chosen on the panel.

    Position SGI windows in exactly the specified place.

    Draw degenerate polylist (OFF) objects correctly for Next and RenderMan:
        use points and lines where they have 1- or 2-vertex "faces".

    Correctly handle lights whose positions don't lie within the model space
        (as the default lights are) in hyperbolic & spherical shaders.


Geomview, Saving:
    Save window positions when saving cameras in command form.
    Use a unique name when saving geom objects as commands; avoids the problem
        of saving as object X and having it automatically renamed X<n> in case
        of conflict, making further commands ineffective.

Geomview, RenderMan:
    Include both NeXT and SGI (etc) standard shader directories; we don't
        know where .rib files will be rendered.
    RenderMan saving no longer enforces adding four-digit numeric suffix.

Geomview, Communications:
    GCL command files containing multiple commands now work sensibly:
        geomview always reads entire contents, one command per display loop.
        (Use (progn ... ) to swallow all at once.)

    emodule-run command: all e-module directories are appended to $PATH
        when the program is started, so emodule-run may mention module programs
        without requiring full pathnames.

    Both SGI and NeXT versions can read from either named pipes or UNIX-domain
        sockets; -M[gc][sp] command-line option specifies data type and
        communications mechanism.


    Software shading now implements fog; density set by lighting attenconst.

    External-module programs are invoked by their full path names when possible.

    Allow L)ooking at cameras.

    Allow reading either geometry or commands from either UNIX-domain sockets
        or named pipes, using '-M[gc][sp] name' command-line option.
    (camera-prop) command specifies how to draw other cameras.
    (cursor) command (for SGI) controls GL cursor and/or loads from .pbm file.
    (setenv) command allows setting environment of e.g. external modules.

    Assorted bug fixes.


Utility programs:

    New programs ucdtooff, anytoucd convert AVS "UCD" format to/from OOGL.

    Anytooff accepts (multiple) arguments, and combines their contents.


Mathematica to OOGL software:
    Improve installation document; be more robust about locating math2oogl,
        geomview, etc. executables, and warning the user if we can't.
        Allow specifying user name when displaying on remote host.
    Don't fail if graphics contain complex values (just plot real part).
    New BezierPlot[] in BezierPlot.m allows plotting Bezier patches directly.


FORMS:
    Include FORMS-2.0-PATCHES, all differences from FORMS 2.0 release.
        Change summary:

  FORMS Library:
    New color-picker module.

    New fouraxis module, derived from positioner.c.
    Allows specifying a direction in 4-space.

    Be more intelligent about frozen forms: only redraw if
    some object changed while the form was frozen.
    Use the sign bit of the form->frozen field to tell.

    Add '@I' prefix to embed FL_ICON_STYLE (symbol font) items in a browser.

    Tie mouse (x,y) position to all mouse clicks.  Use this to ensure that we
    always register a mouse click in its correct position, not the place where
    the mouse lies when we get a chance to read it!
    Click position is fed to the next caller to ask for the mouse position
    after a click; later calls read the live mouse position.  Seems to work.

    Cache stuff as much as possible.  Don't load fonts or read color map unless
    (until) we actually need them.  Might allow programs to start up at
    a reasonable speed, since the SGI font manager is slower in 4.0.x than 3.3.

    Handle Icon font usefully -- use the Symbol font, and allow it to be scaled.
    Accommodate new font-sizing rule in IRIX 4.0.5: fonts are now
    scaled to constant real size rather than constant size in pixels.
    On IRIX 4.0.5 or greater, we discover the error this will cause and
    scale all font sizes by its reciprocal (!).

    Optimize drawing bitmaps.  Cache fl_getmcolor() values; use pointers to
    scan input & output pixel arrays.  ~sixfold speedup.  Save 64K data size.

  FORMS designer:
    Add fdesign2c, batch-mode translator from *.fd to *.{c,h}.
    Added colorwheel and fouraxis objects.


1.3.2   March 1, 1993

        Fix RenderMan file saving bug.
        New OOGL classes: discrete groups and spheres.
        Underlying support for stereo added.
        Fix replace world bug.
        Rotate about CENTERID, not the target geom, in orbit mode.
        Add slow-motion controls (invoked with Shift key).
        Scaled translation procedures now take world size into account, 
          not distance from target object. Use this mode in fly and orbit.
        Add "emodule-defined" command: returns the given emodule's
          shell command (& tests whether any such is defined).
        Add cull-backface as a command.

1.3.1   January 31, 1993

        IMPORTANT: the "pick" command has changed completely and is
        incompatible with previous versions.  If you have an external
        module that uses the "pick" command you should change it to
        use the new "interest" command instead.

        Change the way system-dependent information is specified;
        everything is now specified in the "geomview" shell script
        which sets environment variables and then invokes the binary.
        Nothing that is system-dependent (e.g. pathnames) are compiled
        in; not even default values.

        External modules now appear in alphabetical order in the
        applications browser.  Geomview finds out about them via files
        named .geomview-* in the modules directory, rather than in the
        system-wide .geomview file.  So there is no need to edit the
        system-wide .geomview when installing a module now.  See
        man/cat1/geomview.1 for more information on how to install a
        module.

        The space browser is now on the main panel.

        Different models of hyperbolic space are now available: virtual
        (the insider's view of the projective model), projective (outsider's
        view), and conformal-ball.  The conformal-ball model is only partially
        implemented; it works only for polylist (OFF) objects and only in
        constant-color and smooth-shading modes (not in flat-shading mode).
        The model is per-camera attribute and is settable via a browser in
        the camera panel.

        The camera, when drawn, now fits inside the unit sphere.

        Fixed RenderMan saving bug: file is now opened properly.
        
        "Fly" mode now uses scaled z-translation.

        A color wheel replaces the RGB sliders for picking colors.

        Several "look" functions added for positioning a camera to look at
        an object.  "Look At [L]" button added to tools panel positions
        the current camera to place the target object nicely in the view.
        Look At and look-encompass compute and use a bounding sphere for the
        object rather than using its bounding box.

        Add "Orbit [o]" mode.  Like fly mode, but rotates the camera
        about the center of the selected object.

        Better error reporting; syntax errors in input files are now reported
        with messages including the input line where the error was detected.

        Picking code improved; picking now works in more cases than before.
        Still broken if any part of any object is behind the camera plane.

        Null geoms now allowed, denoted { }.

        Added "interest" command which allows external modules to
        express interest in a command; the module is then notified
        whenever geomview executes the command.  Useful for modules
        that need to know when things in geomview happen.

        Reduced sensitivity to accidental mouse twitches -- it's now
        easier to make an object stop moving.

        Motion now proceeds wrt real elapsed time.  transform-incr
        allows specifying rate of motion.
        
        Control over when commands are executed: sleep-for, sleep-until,
        clock, set-clock, time-interest commands.

        A "load" command simplifies reading files.

        Added stereo viewing support: hardware, crosseyed, red/cyan modes.
        (An external module is needed to control it.)

        Lights may be specified (from command language only) in camera or
        object coordinates, as well as world coordinates.  Allows depth cueing.

        "emodule-transmit" command allows sending messages to running modules.

        "real-id" gives an object's canonical name.

        "all" gives a list of all items (geometry, emodules, ...) of a kind.

        "soft-shader" selects whether to use new software shading.
        New "v~" keyboard shortcut does, too.

        "echo" can be used to print results of evaluating lisp expressions.

        Now reads all commands from command files; used to sometimes read
        only the first command.

        Modules may continue sending messages after being killed.
        Modules receive SIGHUP signal when killed.


1.2.3   October 22, 1992

   Geomview:
        Add outside-hyperbolic space mode ("mo" keyboard shortcut).
        "mh" still selects a view inside hyperbolic space.

        A "spherical" language keyword ``(space spherical)'' is now recognized.
        Implementation of spherical motion is improved.

        Do a better job of adjusting camera setup when switching spaces.

        The first directory in the "Files" browser is initially selected,
        so its files are visible when the panel is first displayed.
        (This directory is the first one given to "load-path", by default ".").

        A new "Vects" button and "aV" keyboard shortcut select whether
        vect objects (lines and points) are visible; they're now controlled
        separately from polygon edges.

        Make hyperbolic translation behave better when the center-of-motion
        is literally "target" (the default); such translations are now along
        an axis through the origin, avoiding spurious rotation.
        If "center" is anything else, it's taken at face value.

        Use color to indicate status of Appearance-panel buttons:
        highlighted yellow when true, gray when false.
        Buttons lie flat on the panel if they've never been changed,
        and depressed if they have been.  (The "Revert [ax]" button restores
        the never-set status, and shows objects as they naturally appear.)

        Add half-baked transparency: "aT" keyboard sequence.

        Fix supersensitive behavior of Applications browser;
        running modules now appear in boldface red.

        Add "-nopanels" command-line option.

    trigrp:
        Switch between euclidean and hyperbolic space when changing groups.

    FORMS library:
        Adapt to new IRIX 4.0.5 font manager's sizing behavior.
        Since FORMS panels are fixed in pixel units, we rescale fonts
        to be constant pixel size rather than 4.0.5's constant real size.
        [Still works on older systems.]

    External modules in general:
        A list of all external-module definitions is now kept in
        "data/.geomview-modules"; it's automatically updated when
        new modules are installed in the geomview binary directory.
        It's also safe to edit this file by hand.

    General distribution:
        Distributed files are now writable by the owner, to make it
        easier to apply upgrades.  Once this 1.2.3 distribution package
        is installed, it should be possible to install future distributions
        without being the superuser, since "tar" will be able to overwrite
        the old files.


1.2.2   October 3, 1992

   Geomview:
        Repaired ANSI C incompatibilities -- this version compiles
            under Irix 4.0.4.
        Several memory leaks were fixed.
        Don't corrupt memory when new-geometry command is used.
        Avoid crashing when a camera is deleted.
        Bezier patch dicing level is now properly recorded and
            applied to newly loaded Bezier objects.
        Bezier's saved in RenderMan format are written as true patches,
            not polygonal meshes.   Texture coordinates also saved for STBBP's.
        Don't lose commands sent by external modules just before they die.
        Don't continuously redraw the display when camera drawing is on.
        Make hyperbolic translation, which was approximately correct, exact.
        Repair "position", "position-at", "position-toward" commands.
        Fix -b (background color) command-line option.
        Added performance metering (control-T keyboard character).

    Libraries:
        New libformsx.a library has some handy FORMS-related functions:
          enabling/disabling objects, reading numbers from input fields, etc.
        
        Maximum Bezier degree is now 12 rather than 6.
        Bounding boxes of Bezier patches now at least fairly meaningful.

        Avoid crashing when encountering erroneous OFF files.

        Invert the sense of QUAD normals to be consistent with other objects.

    Makefile configuration:
        Removed "make lib" warning in multiple-source library directories.
        Ensured that the FORMS library is installed by the time it's needed.
        
        
1.2.1   September 17, 1992

        Fixed a problem with src/lib/forms/Makefile which prevented
        successful compilation on systems that don't already have the
        FORMS library installed.

        1.2.1 is not really a new release --- it's just a re-packing
        of the tar file with a new src/lib/forms/Makefile.

        [ Details of the problem: modified src/lib/forms/Makefile so
          that it installs libforms.a in bin/sgi upon "make all"
          rather than just "make install".  This is now consistent
          with the way the other .a files are installed, and fixes a
          problem which prevented successful makes on systems that
          don't already have FORMS installed.  In previous releases
          libforms.a was installed by geomview/gl/O.sgi/Makefile
          before it attempted to link geomview; in 1.2, however, the
          "example" program links with libforms.a but doesn't install
          it first.  Since "e" comes before "g", "example" is compiled
          by "make all" before geomview, with the result that the
          compilation fails since libforms.a is not yet in place.

          I created geomview-1.2.1.tar.Z by unpacking the 1.2 tar file
          into a fresh dir, replacing the files ./src/lib/forms/Makefile
          and ./CHANGES (this file), and re-packing.  ]


1.2     September 4, 1992

Panels
------

New iconic tool panel replaces parts of old main panel. 

"Zoom" now changes camera field of view: add "scale" to change size of
geometry. (Can also change apparent size by z-translating object or
camera.)

Reorganized panels. Camera panel has camera-related things, appearance
panel has geometry-related things. Obscure panel now only has
normalization and space things.

Add save panel. Now through user interface can save: Renderman or .sgi
snapshot, text file of commands, geometry, cameras, transforms,
windows for any (or all) objects, and position information for all panels. 

Appearance controls now override all lower levels (before if lower
level had appearance of its own it was left unchanged). Added revert
button to appearance panel.

New "?" button on main panel same as "?" keyboard shortcut (dumps
keyboard shortcut summary to tty).

Add "CSmooth" mode to shading browser of appearance panel.
This is a constant-shaded style (shading depends only on vertex colors, 
not on lighting) but with smooth interpolation where colors vary across
a face.



Keyboard Shortcuts
------------------

Lines-closer shortcut "ac" now also "vc" since it's a per-camera
option at the moment.

Add backface culling (only accessible through keyboard toggle "vb"). 

"g" keyboard prefix now picks world not most recently picked geometry.

"." new prefix for target object, i.e. "self". 

"P*" keyboard shortcut to bring up panels. 

"[se|sh]" shortcut changed to "[me|mh|ms]". (m for metric since s for
space got taken over by "scale"). 

"TV" toggles NTSC video mode.

"vs" toggles single vs. double-buffered windows.


Commands
-------------

Add complete help messages for all command language functions and new
commands "?" and "??".

The syntax of the write command has changed. See geomview.5.

Added position, position-at, position-toward commands. 

Added rawevent, winenter, freeze commands (intended for development
not for general use.)

External module command name changes:
emodule-define is the new name for ui-emotion-program.
emodule-start is the new name for ui-emotion-run.
emodule-run is the new name for "|".

Eliminated ui-emotion-modename: awkward event-shipping to external
modules.  More useful access to functionality that is presently hidden
internally is under development now.


Motion
-------

Totally new motion paradigm. Most old functions are mimicked. New
functionality added. Can now specify a center of motion (orbit mode
used to be camera around center of world: now can be any object
orbiting any other object. See "ui-center" command.). Can specify
rotations and translations in x, y, z instead of a raw 4x4 matrix (see
"transform*" commands).

Fly mode changed yet again: now left mouse rotates camera, middle
mouse flies camera forward/backward.

Flight Sim mode eliminated.



External Modules
----------------

Distributing external modules separately from geomview proper, except
for a few examples.

Added example external module with accompanying tutorial document.

Improved handling of external modules; can now run multiple concurrent
modules and can finally terminate them. See command language changes above. 

External modules MUST now run in the foreground, lest geomview think they've
died.  FORMS/GL modules need to call foreground().  See emodule-run
documentation in geomview(5).

Do a better job of killing off external modules when geomview exits
and suspending them when geomview is suspended.

Can now invoke external modules from geomview's command line and can
pass (globbed) parameters through to their command lines.



Geomview general
----------------

Better Renderman support, especially for automated generation of movie
frames. Can specify whether to render directly to framebuffer or to a
tiff disk file. Can give file prefix which is then autoincremented on
each Renderman snapshot. Tiff file name is constructed from rib file
name (used to always be called "image.tiff").

Snapshot pops window to prevent obscuration, and redraws in singlebuffered
mode to minimize dithering artifacts, and to avoid a "scrsave" bug which
sometimes caused the previous image to be saved.

In hyperbolic mode the camera starts out inside the sphere instead of
outside the sphere, and the bounding sphere is not automatically drawn. 

Add spherical space mode.

Add new special id's: self, universe, primitive (for coordinate systems).

Pick data can be written in any of several coordinate systems.

Make picking work on views with dedicated scenes.

Better camera geometry for default camera drawn. (Development feature
that may change in the future: uses "cam.oogl" file instead if it
exists.)

Number new objects according to their id, so camera c2 == "Camera<2>",
etc.



OOGL
----

Better error detection and recovery in OOGL loading rountines.

Added method extension mechanism for geom objects.

Various internal reorganizations --- renaming variables, etc.

Added support for variable-length arrays (vvec's).

Added geom transform methods.

Print a useful error message if a camera file can't be found.

Fixed binary mesh loading bug; binary meshes now load properly.

Fixed bug which caused sometimes-wrong screen z computation associated
   with picking.

Fixed picking of closed VECT object.

Don't draw VECTs when edge drawing is off.

Objects loaded from files are no longer tied to the contents of those files;
the sequence "load object, change file, load other object from same file"
now yields two distinct objects, not two identical copies of the new version.

General
-------

Made source code more ANSI-compliant.

Many optimizations; code runs faster.

Fixed bugs assocaited with communication via pipes; close them

Fixed bugs associated with reference counting and memory
   allocation and freeing.

New configuration setup; more robust

Overhaul Makefile structure; rely more on common Makefiles
   referenced via "include"

Completely new lisp interpreter; much more general and easier to
  use than previous version.  See the man page man/cat3/lisp.3 for
  details.

Fixed various minor bugs.



Known problems:
---------------
Spherical mode doesn't work on VGXes.

Zoom and Scale have no inertia.

Constrained motion (to X or Y axis) no longer works.

Sometimes core dumps on bad input files.

-------------------------------------------------------------------------------
1.1     May 27 1992

    Slightly better documentation; lang.doc renamed geomview.5.
    Four more sample external modules added.
    Control panel settings override objects' own appearances.

    Object vertex/edge/face picking (rightmouse), w/command-language feedback.
    New flight-simulator motion mode.
    More state-saving operations, 'write' and 'snapshot' language commands.
    Command-language control over windows & panels (placement, visibility).
    Can save scenes in RenderMan .rib format.

    Many bug fixes including:
      Memory should now be freed properly when objects are deleted.
      Code now compiles under IRIX 4.0.1 ANSI C.
      Input panels now accept input properly under 4.0 (input focus bug fixed).

    Known problems:
      IRIX 4.0 remote display (DGL) doesn't work; geomview must run on the
        machine where it's displaying.

-------------------------------------------------------------------------------
1.0.1   February 25 1992:       

    Miscellaneous minor bug fixes
    Slightly better documentation

-------------------------------------------------------------------------------
1.0     January 31 1992

    initial release
